A statement tells. A question asks. A command tells someone to do something. An exclamation shows strong feeling. The end mark is your clue.
A complete sentence has a subject and a predicate and one complete idea. A fragment is missing a piece. A run-on jams two sentences together without the right punctuation.
The SUBJECT is who or what the sentence is about. The PREDICATE tells what the subject does or is.
A simple sentence has one complete idea. A compound sentence joins two complete ideas with a comma and a FANBOYS word (for, and, nor, but, or, yet, so).
A noun names a person, place, thing, or idea. A common noun is general (dog); a proper noun names a specific one and is capitalized (Rover). An abstract noun names an idea you can't touch (joy).
Add -s to most nouns. Add -es after s, x, z, ch, sh. If a noun ends in a consonant + y, change the y to i and add -es.
An action verb shows what the subject does. A helping verb (like is, are, was, will, have) works with the main verb.
A singular subject takes a singular verb (the dog runs). A plural subject takes a plural verb (the dogs run).
Present = happening now. Past = already happened (often add -ed; some verbs are irregular). Future = will happen (use 'will').
Use 'a' before a consonant sound and 'an' before a vowel sound (a, e, i, o, u). Use 'the' for a specific one.
A preposition shows where or when something is (in, on, under, over, behind, near, before). A prepositional phrase is the preposition plus the noun it points to (under the bed).
Coordinating conjunctions (FANBOYS: for, and, nor, but, or, yet, so) join equal parts. Subordinating conjunctions (because, although, when, while, since, if, after, before, until) start a dependent idea.
A contraction shortens two words with an apostrophe in place of the missing letters (do not → don't, I am → I'm).
Use commas to separate items in a series, to set off the date and the year, between a city and state, and after introductory words or a direct address (a person you are speaking to).
Capitalize the first word of a sentence, the word I, people's names and titles, days, months, holidays, and the names of specific places. Do NOT capitalize seasons or general words.
Adding endings changes spelling: drop the silent e before -ing/-ed; double the final consonant after a short vowel; change y to i before most endings; add prefixes (re-, un-) and suffixes (-ful, -less, -ly, -ness, -y).
