مقایسه چیزها (بزرگتر، گرانتر)

Double the last letter for one-syllable words that end in a single vowel + single consonant (like `big` -> `bigger`, `hot` -> `hotter`). Do not double it if there are two vowels (like `cheap` -> `cheaper`).

Both are correct! In American English, `farther` is usually for physical distance and `further` is for metaphorical distance (like 'further information'). In British English, `further` is common for both.

Both are actually correct! Some two-syllable words like `clever`, `simple`, and `narrow` can take either form, though `-er` is more traditional.

Because `better` already means 'more good'. Saying `more better` is like saying 'more more good', which is redundant and incorrect in standard English.

`Than` is for comparing things (He is taller `than` me). `Then` is for time or sequences (I went home, `then` I ate dinner).

Use the structure `as + adjective + as`. For example, 'I am `as tall as` my brother.'

Yes! For example, 'He runs `faster` than me' or 'She speaks `more clearly` than her friend.' The rules for syllables are the same.

You can use `less + adjective + than`. For example, 'This phone is `less expensive` than that one.'
