How to write a sentence.

A subject is a person, place, or thing.  A predicate is an action.

"I" is the complete subject. "Went to the store" is the complete predicate.

In the sentence the simple subject is "we". "Saw" is the simple predicate.

These words are: and, nor, but, for, yet, so, and or.

"Or" is the conjunction.

"But" is the conjunction.

Past tense is when it's already happened.

Present tense is when it's happening right now.

Future is when it will happened.
