Begin the sentence with a capital (uppercase) letter.
Add a noun to the sentence. The noun is a person, place or thing and tells the reader who or what did an action. Example of nouns include "mom," "school," "dog," "child" and "computer."
Add a verb to the sentence. The verb tells the reader what action the noun is doing. Examples of action verbs include "mix," "run," "see" and "jump."
Add an object after the verb. According to Dictionary.com, an object is "a noun, noun phrase, or noun substitute representing by its syntactical position either the goal of the action of a verb or the goal of a preposition in a prepositional phrase."
Add prepositions, words that show the relation between one word and the object. Place prepositions before nouns. Examples of prepositions include "about," "in," "of," "near," "under" and "with."
Insert conjunctions, words that pair elements in a sentence together. Examples of conjunctions include "and," "because," "either" and "or."
Add articles, which are adjectives placed before a noun to identify a reference to a specific word. The Guide to Grammar and Writing states examples of articles include "the," "a" and "an."
Add infinitives to add clarity to a sentence. An infinitive is a type of verb that has the word "to" next to a main verb (for example, "to run" or "to make").
Add a punctuation mark to the end of the sentence. The punctuation mark is the last step of completing a sentence after adding prepositions, conjunctions and other parts of speech and indicates the idea is complete. Punctuation marks include periods (.), exclamation points to express excitement (!) and question marks (?).
