Sentence diagraming theoretical

Diagraming a sentence is a great exercise to gain a deeper undenstanding of its gramatical stature. A sentence diagram is a visual representation of a sentence's structure and its words functions. (A Diagram is a picture of a sentence)

When Diagraming sentences, the horizontal line under the subject and predicute is called the base line. The subject is written on the left side of the base line, and the predicate is on the right side of the base line. A vertical line that crosses the base line is drawn between the subject and the verb, Punctuation is not used in a sentence line

Compound subjects are both written on the left side of the base line.
The conjunction that connects the two subjects is written on a dotted line between the two subject lines.

Sentences with compound Subjects and compound verbs have the subjects written on the two lines on the left side of the baseline, and the verbs are written on the two lines on the right side of the baseline. The conjunction that connects the two subjects is written on a dotted line between the two subjects, and the conjunction that connects the two verbs is written on the dotted line between the two verbs.

when the subject is understood, as in commands, it is written on the left side of the baseline in parenthesis.

When diagramming sentences, the adjective is written on a line under the word the adjective modifies. Articles are written on a line under the word to which they refer.

when diagramming sentences, the adverb is written on a line under the word the adverb modifies.

compound adverbs are written under the word they modify, and the conjunction is written on a dotted line connecting them.

when diagramming sentences the direct of object is written on the baseline to the right of the verb. The dividing line does not cross the baseline.

Compound direct objects are written on the baseline to the right of the verb. Each direct object is written on its own line connected to each other by the conjunction which is written on the dotted line.

when diagramming sentences that indirect object is written on a line under the verb.

Compound indirect objects are written under the verb on two lines connected by the conjunction on a dotted line.

Word that modifies nouns and pronouns. Adjectives tell what kind of, which one, or how many.

Word that modifies verbs, adjectives, or other adverbs. Adverbs tell how, where, when, and to what extent

A noun or pronoun that follows a noun or pronoun to give more information.

An appositive in a phrase that explains the noun or pronoun.

A sentence with two or more independent clauses.

receives the action of the verb. It answers the question whom or what?

A verb ending in ING and used as a noun.

precedes the direct object, and tells to whom or to what.

names a person, place, thing, or idea.

A verb used as an adjective

The sentence part that says something about the subject. It contains the verb or verb phrase.

An adjective that follows a linking verb and modifies the subject.

an noun that follows a linking verb and modifies the subject.

Word that takes the place of a noun.

A group of words that express a complete thought; has a subject and a predicate.

A sentence with just a subject and a verb.

A person, place, thing, or idea that the sentence is about

Word that expresses action or a state of being.

when diagramming sentences, the prepositional phrase is written below the word it modifies on a line with an extra extension. The object of the preposition is written on an horizontal line, and the adjectives used in the prepositional phrase are written on the lines that come off the object’s line.

when diagramming a prepositional phrase that modifies other prepositional phrase, the first phrase is written off the word modifies, and the second phrase is written off the word modifies.

When diagramming sentences with prepositional phrases that have compound objects of a preposition, the compound objects are written on the two lines coming off the preposition. A dotted line connects the two lines, and the conjunction is written on it.

when diagramming sentences, the participle is written under the word it modifies. The participle is written in a curve, starting on the angled part of the line, and continuing on the horizontal part of the line.

When diagramming a participle phrase, the phrase is written under the word it modifies.

when diagramming a sentence with gerunds, the gerund is written on the line and the object of the gerund (if there is one) is written after it, divided by a line like that of a direct object, the gerund is written in the curve around the right angle of the line. since gerunds can be many parts of speech, this diagram is placed in the part of speech.

when diagramming infinitives that are used as modifiers, write the diagram as you would for a prepositional phrase.

when diagram infinitives that are used to nouns, the diagram goes in the same place as the noun would.

When diagramming predicate nominatives or predicate adjectives, you write the word on the same line as the simple subject and the verb it is written after the verb. The line dividing the verb from the predicate nominative or the predicate adjective does not cross the baseline and slants back towards the subject to show the connection.

when diagraming compound sentences, each independent clause is diagramed as a sentence. The diagrams are connected by a dotted step line with the connecting conjunction, written on the horizontal part of the line the diagrams are connected at the verbs.
