Common mistakes to avoid
1. Fit (US) or fitted (UK)
In American English, the Past Simple is usually fit (no change). In British English, it is usually fitted (regular). Both are correct: The jacket fit me (US), The jacket fitted me (UK).
2. Fit ≠ suit
Fit = to be the right size. Suit = to look good on someone (style, colour, personality). You need both words when you go shopping: It fits me, but the colour doesn't suit me.
3. Fiting ❌
The -ing form doubles the t: fit → fitting, never fiting. It is the same with put → putting, cut → cutting and sit → sitting (a short vowel before one final consonant).
