Usage

The adverb that goes with good is well: she sings well, not she sings good. After feel, look, smell, sound, and taste you use the adjective: I feel good, it tastes good. In American speech I'm good also means no, thank you: More coffee? I'm good, thanks. Good on its own is a reply that shows you are pleased or satisfied.

Common mistakes

She speaks English very good. She speaks English very well.
Good is an adjective; the adverb is well.
This one is more good. This one is better.
The comparative and superlative are better and best, not more good or goodest.
I'm good in math. I'm good at math.
The preposition after good in the skill sense is at, or with for people and things you handle.

For translators

Meaning across languages Good covers quality, skill, pleasure, kindness, usefulness, and amount; most languages split these across several words, so check the sense before choosing an equivalent. Fixed greetings (good morning) and formulas (good for you) do not translate word for word.
Grammar trap The comparative and superlative are better and best, never gooder or more good. Good is an adjective; the adverb is well, except after linking verbs such as feel and taste, which take good.
Pronunciation trap The vowel is the short u of put and book, ʊ, not the long oo of food: good rhymes with wood and should. The final d stays a d sound, not t.
