Rule #01

Subject-Verb Agreement

A singular subject takes a singular verb; a plural subject takes a plural verb — always, no exceptions.

"She runs every day."
"She run every day."
12
Rule #12

Using "A" vs "An"

Use "a" before consonant sounds and "an" before vowel sounds — it's about the sound, not the letter.

"An hour ago, a hero arrived."
"A hour ago…"
29
Rule #29

Avoid Double Negatives

Two negatives create a positive meaning in English — a very common and confusing mistake.

"I don't know nothing."
