Common mistakes	Confused with 'capable' — they are similar but not interchangeable., Using 'able' without 'to' when following it with a verb., Incorrectly using 'able' with a past event.	'Fit' is often confused with 'fitted' — 'fit' describes the state, 'fitted' describes the act of making something fit., Some learners forget to use the preposition 'into' when discussing fitting in a space (e.g., 'fit into the box')., Using 'fit' as a noun instead of a verb can lead to confusion, as it mainly functions as a verb.
Usage notes	Use 'able' to express capability in a neutral context. It’s appropriate in both spoken and written English but avoid using it in overly formal situations.	Use 'fit' when discussing whether something matches well or is suitable. It's neutral, so it can be used in both casual and formal conversations. Avoid using it when discussing emotional or abstract concepts; it’s more about physical or practical suitability.
