Countable nouns have singular and plural forms (a book / two books). Uncountable nouns (water, information, advice) do not — they take singular verbs and cannot use 'a/an'. Use 'some', 'much' or 'a piece of' with uncountables.
Use the present simple for habits, routines and permanent facts. Use the present continuous for actions happening now or around now, and for temporary situations. State verbs (know, believe, own) are usually not used in continuous.
Present perfect connects the past to now: unfinished time, life experience, or recent past with present result. Past simple is for finished actions at a finished time (yesterday, in 2019).
Use 'a/an' for singular countable nouns mentioned for the first time or when the item is one of many. Use 'the' when both speaker and listener know which one, for unique things, and for superlatives.
'At' for exact points (at 6pm, at the door), 'on' for days and surfaces (on Monday, on the table), 'in' for enclosed spaces and longer periods (in the room, in July, in 2026).
Modals like 'may', 'might', 'could' express possibility now or in the future. 'Must' expresses strong deduction. 'Can't' is the negative deduction.
Short adjectives take -er / -est (fast, faster, fastest). Longer adjectives use 'more' / 'most' (interesting, more interesting, most interesting). Irregulars: good/better/best, bad/worse/worst.
In reported speech, tenses usually shift back one step (present → past, will → would). Time and place references also change (today → that day, here → there).
Dictionary pages connect definitions to part of speech, usage notes, examples, citations and related words so learners can see how a word behaves in real English.
