Grammar rules, explained simply

Tap a card to expand the rule, then try the quick exercise to check your understanding.

Present Simple vs Present Continuous

Use the Present Simple for habits and facts ("She walks to school"). Use the Present Continuous for actions happening right now ("She is walking to school").

Choose the correct form: "Listen! The baby ___ (cry)."

Subject–Verb Agreement

A singular subject takes a singular verb; a plural subject takes a plural verb. "The list of items is on the table" — "list" is singular, so use "is".

Choose the correct form: "Each of the students ___ a book."

Articles: A, An, The

Use "a" before consonant sounds, "an" before vowel sounds, and "the" when referring to a specific, already-known noun.

Choose the correct article: "She is ___ honest woman."

Past Tense Irregular Verbs

Irregular verbs don't take "-ed" in the past tense. "Go" becomes "went", not "goed". These must be memorized individually.

Choose the correct past tense: "Yesterday, I ___ to the market."
