Diagramming sentences might seem complicated at first, but you'll quickly get the hang of it with this comprehensive guide. Sentence diagramming helps you visually understand the function of every part of a sentence, which helps you construct better sentences and improve your writing. Once you understand the essentials, diagramming a sentence is as fun and addictive as your favorite puzzle.
Things You Should Know
- Start by diagramming a simple sentence with a subject, verb, and direct object . For example, the sentence “ Students read books. ”
- Draw a horizontal line that’s split in the middle by a vertical line. Write the subject on the left side of the vertical line and the verb on the right side.
- On top of the horizontal line, draw another vertical line on the right side of the verb. Write the direct object on the right side of this new vertical line.
Steps
Sample Diagram Worksheets
-
Diagram the subject noun and predicate verb. Draw a horizontal line with a small vertical line through the middle. To the left of the vertical line, write your subject. To the right of the vertical line, write your verb. This is the most basic complete sentence. [1] X Research source
-
2Add the direct object. Draw another vertical line going upward from the horizontal line. To the right of this line, write the direct object.
- In the above sentence, Vegetables disgust Felipe:
- The subject is “vegetables.”
- The verb is “disgust.”
- The direct object is “Felipe.”
Advertisement - In the above sentence, Vegetables disgust Felipe:
-
3Add the indirect objects beneath the verb. Draw a small horizontal line under the verb and connect it to the base line with a diagonal line. In general, indirect objects could include a preposition, and so are drawn with a diagonal line coming off of the word they modify. See Step 6 for prepositions. [2] X Research source
- In the above sentence, The farmers gave their kids fresh vegetables:
- The subject is “farmers.”
- The verb is “gave.”
- The direct object is “vegetables.”
- The indirect object is “kids.”
- The article is “the.”
- The possessive pronoun is “their.”
- The adjective is “fresh,” which modifies “vegetables.”
- In the above sentence, The farmers gave their kids fresh vegetables:
-
4Draw a slash to add a predicate nominative or predicate adjective. A predicate nominative is a noun, pronoun, or adjective that refers to the subject. The verb preceding the predicate nominative or adjective is usually a linking verb, such as the forms of to be ( is , are , was , etc.) or sense words ( looks , smells , tastes , etc.). To the right of the slash, write the predicate nominative or adjective.
- In the above sentence, Vegetables are disgusting:
- The subject is “vegetables.”
- The linking verb is “are.”
- The predicate adjective is “disgusting.”
- Note that pronouns following linking verbs should be in the nominative case: This is she or It is I rather than This is her or It is me .
- In the above sentence, Vegetables are disgusting:
-
5Add modifiers and articles. Place adjectives, adverbs, articles, and possessives on diagonal lines below the words they modify.
- In the above sentence, The green vegetables are always disgusting:
- The subject is “vegetables.”
- The linking verb is “are.”
- The predicate adjective is “disgusting.”
- The adjective is “green,” which modifies “vegetables.”
- The article is “the.”
- The adverb is “always,” which modifies “disgusting.”
- In the above sentence, The green vegetables are always disgusting:
-
6Add a participle on a bent line beneath the word it modifies. Write the participle as a curved word on this slanted line, as shown in the example below.
- In the above sentence, Working farmers enjoy vegetables:
- The subject is “farmers.”
- The participle is “working,” which modifies “farmers.”
- The verb is “enjoy.”
- The object is “vegetables.”
- In the above sentence, Working farmers enjoy vegetables:
-
7Add a preposition. Draw a diagonal line coming down from the word it modifies, whether a verb or adjective or other part of speech. Write the preposition on this diagonal line. Draw a horizontal line coming off the preposition line. Write the object of the preposition on this horizontal line.
- In the above sentence, The kids threw the vegetables in the trash:
- The subject is “kids.”
- The verb is “threw.”
- The direct object is “vegetables.”
- The preposition is “in.”
- The object of the preposition is “trash.”
- The article(s) are every instance of “the.”
- In the above sentence, The kids threw the vegetables in the trash:

1Diagram a compound sentence made up of two independent clauses. Add the conjunction on a bent, broken line. [3] X Research source
- In the above sentence, The green vegetables are always disgusting, and I hate them, there are two independent clauses.
- The subject of the first clause is “vegetables,” the verb is “are,” the predicate adjective is “disgusting,” the article is “the,” the adjective is “green,” and the adverb is “always.”
- The subject of the second clause is “I,” the verb is “hate,” and the direct object is “them” (a pronoun referring to the already-stated “vegetables”).
- The two clauses are linked by the coordinating conjunction “and.”
-
2Diagram a simple sentence that includes a conjunction by splitting the line. Then, join the split lines with a broken line. This format is used if the conjunction is joining words within a simple sentence.
- In the first of the above sentences, I like fruits and vegetables , the subject is “I,” the verb is “like,” the two direct objects are “fruits” and “vegetables,” and the conjunction is “and,” which joins the two direct objects.
- In the second of the above sentences, Green and yellow vegetables are always disgusting , the subject is “vegetables,” the verb is “are,” the predicate adjective is “disgusting,” the adverb is “always” (modifying “disgusting”), the adjectives are “green” and “yellow” (modifying “vegetables”), and the conjunction joining the adjectives is “and.”
-
3Draw appositives in parentheses next to the words they modify. Appositives are words that redefine or rename other words. Appositives can be separated in sentences using colons, dashes, or parentheses and do not change the meaning of the sentence. Adjectives and articles that apply to the appositive are drawn beneath the appositive word.
- In the above sentence, An unabashed herbivore, I like fruits and vegetables:
- The subject is “I.”
- The verb is “like.”
- The direct objects are “fruits” and “vegetables.”
- The conjunction joining the direct objects is “and.”
- The apposition to “I” is “herbivore.”
- The article is “an.”
- The adjective is “unabashed,” which modifies “herbivore.”
- In the above sentence, An unabashed herbivore, I like fruits and vegetables:
-
4Place infinitive phrases on a separate line beginning with a diagonal. This infinitive line is called a “pedestal.” Infinitives are the basic forms of verbs, often beginning with the word to , as in to see or to walk or to eat . [4] X Research source
- In the above sentence, I like to eat vegetables, the subject is “I,” the verb is “like,” and the infinitive phrase is “to eat vegetables.”
- The infinitive phrase “to eat vegetables” is made up of the infinitive verb “to eat” and the object “vegetables.”
-
5Draw a staircase for gerunds. Gerunds are verbs ending in -ing that act as nouns but often take direct objects. They are usually drawn on a pedestal or stepped line. [5] X Research source
- In the above sentence, Eating vegetables is good for you , the object is “vegetables,” the linking verb is “is,” the predicate adjective is “good,” the preposition is “for,” and the object of the preposition is “you.”
- The gerund phrase is “eating vegetables,” which is made up of the gerund “eat ing ” and the object “vegetables.”
- Gerunds can also function as objects of prepositions. When functioning as the object of a preposition, gerunds do not need a pedestal.
- In the above sentence, You can achieve a healthier lifestyle by eating vegetables , the subject is “you,” the verb phrase is “can achieve,” the direct object is “lifestyle,” the preposition is “by,” the article is “a,” and the adjective is “healthier” (modifying “lifestyle”).
- The gerund phrase is “eating vegetables,” which is made up of the gerund “eat ing ” and the object” “vegetables.”
-
6Draw noun phrases on pedestals. That , and other expletives like which , can introduce a noun phrase. [6] X Research source
- In the above sentence, I wish that she ate more vegetables , the subject is “I” and the verb is “wish.”
- The noun clause, “that she ate more vegetables” is introduced by the expletive “that.”
- The noun clause is made up of the subject “she,” the verb “ate,” the direct object “vegetables,” and the adjective “more.”
- Noun phrases do not always need an expletive. Sometimes it is simply understood, such as the implied “that” in the sentence I wish she ate more vegetables . When the expletive is understood, draw an X in parentheses where the word would go.

Review the parts of speech . Understanding how to identify a noun , pronoun, verb, adjective, conjunction, preposition, etc. is essential to sentence diagramming. [7] X Research source
- Nouns: Words representing people, places, things, or ideas, e.g. dog , computer , Haiti , teacher , and dream.
- Pronouns: Word that represent nouns, e.g. he , she , they , it , or who.
- Verbs: Action words, e.g. to run , to swim , and to fly.
- Adjectives: Describing words that apply to nouns, e.g. blue in blue water , big in big baby , and smelly in smelly garbage.
- Adverbs: Describing words, like adjectives. However, adverbs apply to verbs, adjectives, and other adverbs. E.g. quickly in quickly run , quite in quite slowly , and very in very beautiful.
- Participles: Words formed from verbs that act like adjectives or nouns, e.g. working in working farmers , flying in flying birds , and flooded in flooded basement. [8] X Research source
- Conjunctions:
Words that join clauses or words within the same clause, e.g. and
, but
, or
, for
, nor
, so
, and yet.
- Joining independent clauses: "Jalissa took the car keys and she drove to work."
- Joining words in the same clause: "Arturo likes apples and oranges equally."
- Prepositions: Words that tell you how nouns in a sentence relate to one another, whether by direction, time, location, or space. E.g. above , on , in , between , through , and to, among others.
- Articles: Words that modify nouns, making them specific or unspecific: a and an (unspecific), the (specific).
-
Review other grammatical components. Some of these are related to parts of speech, while others are more advanced concepts that add meaning and complexity to a sentence. All of these components and their purposes are necessary to understand before you start to diagram sentences. [9] X Research source
- Subject noun: The subject of a sentence is the doer of the action in the sentence. E.g. “Jesse” in Jesse went to the store.
- Predicate verb: The part of a sentence that tells us the complete action of the sentence, which includes the main verb/action. E.g. “was easy” in The test was easy or “knows my father” in The man in the car knows my father.
- Direct object: The noun that receives the action, e.g. “doll house” in Max made a doll house for Ellie.
- Indirect object: The noun that receives the direct object, e.g. “Ellie” in Max made a doll house for Ellie.
- Independent clause: A clause that can stand alone as a sentence, e.g. "He went to the library.
- Dependent clause: A clause that must join an independent clause to become a complete sentence, e.g. “before swim practice” in He went to the library before swim practice.
- Verb phrases:
Main verbs, like lift
, cook
, or drive
, that have been paired with auxiliary, or helping, verbs, like will
, can
, or may
, which create a sense of time and mood in English sentences. In the following examples, the main verbs are bold
and the auxiliary verbs are italic
. The two combined make the verb phrase. Note that adverbs are not part of the verb phrase, even if they occur between the auxiliary and main verbs.
- She will lift the box.
- They can cook dinner for us tomorrow.
- You may not have dessert. ( Not is not part of the verb phrase).
- Sam would have liked this movie. (Depending on the intent, auxiliary verbs can be strung together.)
-
Practice identifying grammatical parts by analyzing sentences . It is much easier to diagram a sentence if you already have an idea of the grammatical contents of that sentence. You can write out and label the different words in the sentence, or you can mentally note which words serve what purpose. Some words are difficult to parse, so save those for last.
- Determine your subject and verb.
These are the foundations of a sentence and, thus, the foundations of a sentence diagram. The subjects of the following sentences are bold
, and the main verbs are italic
.
- Children will listen .
- Though John doesn't like broccoli, he will eat other vegetables.
- Vegetables disgust Felipe.
- Felipe was disgusted by vegetables.
- Ira gave Cho her necklace.
- Find the direct object if there is one. From the above examples, Children will listen does not have a direct object, but Vegetables disgust Felipe does. Felipe is the direct object of the verb disgust .
- Determine your subject and verb.
These are the foundations of a sentence and, thus, the foundations of a sentence diagram. The subjects of the following sentences are bold
, and the main verbs are italic
.

QuestionHow do you diagram "I am secretly correcting your work"?Community AnswerUse the instructions in this article to try it yourself! Hint: "am correcting" is a verb phrase (see Tips) and "secretly" is an adverb modifying the verb phrase; and "your" is a possessive pronoun (see step 3 for an example of a possessive pronoun).

QuestionHow do I diagram a sentence with the word "which" in it?Community Answer"Which" may be either an adjective or a pronoun depending on how it's used. For example, in the sentence "I couldn't decide which cat I like more." which is a relative pronoun denoting a noun clause. In this sentence, "which cat I like more" is acting as a direct object. However, it functions as a clause. When used as a pronoun "which" is often seen in questions where it shows a lack of particular direction, and the predicate is what shows the asker asking for that direction. For example, in the sentence "Which is it?" which is acting as the subject itself. However, it doesn't have to be in a question format, as seen in the phrase "which it is."
-
QuestionHow do you diagram multiple subjects?Community AnswerSee step 7 for conjunction examples. Each subject would get its own line and would be connected by verticle dashed lines, one of which probably has a conjunction written on it. It depends on the specific sentence, but these lines would then be joined to the remainder of the sentence.

Tips
- Split contractions when necessary. [10] X Research source If the word is they're , which stands for they are , the noun is they and the verb is are . If they is the subject, put it to the left of the vertical line, and place ' re to the right of the vertical line.Thanks
- Beginning sentence diagramming can be confusing. Start with short, easy sentences, and build up from there. One of the best ways to learn to diagram sentences is to look at sentences that have already been diagrammed. There are many great resources on the web with hundreds of sentence diagrams, many of which have thorough explanations.Thanks
- Words of direct address are written on separate lines above the subject. For example, in the sentence Chaequan, what would you like for dinner tonight? , Chaequan is a word of direct address, placed above the subject you . Would like is the verb, tonight is an adverb, dinner is the object of the preposition for , and what is the direct object.Thanks

To diagram a sentence, start by drawing a horizontal line with a vertical line through the middle. Next, put your subject to the left of the vertical line and the verb to the right. If the sentence contains a direct object, draw another vertical line that stops at the horizontal line. Then, add the direct object on the right-hand side. You can also place indirect objects beneath the verb. For adjectives and adverbs, put them on diagonal lines coming down from the words they modify.

"Amazing! We did sentence diagrams when I was back at school in the Fifties and I've always regretted not keeping the books. I've been a teacher of English as a foreign language for 40 years, and have always applied the rudiments of what I remember of diagrams to help my students understand word placement and function. Your page has refreshed my memory. I've saved this, and will certainly refer to it in my lessons. Thank you so much!"
