Common mistakesConfused with 'participle' due to similar sound., Using 'partially' when 'completely' was intended., Forgetting to use it with a verb or adjective.'Partly' is sometimes confused with 'part' as in the amount., Some learners use 'partly' incorrectly with a noun instead of an adjective., Mistakenly using 'partly' in place of 'mostly' or 'mainly'.'Somewhat' used incorrectly as an adjective., Confused with 'somewhat like' in contexts where 'somewhat' doesn’t need a comparison., Overusing 'somewhat' in sentences where a stronger adverb is necessary.
Usage notesUse this word when something is done to some extent but not entirely. It's suitable for academic and everyday contexts but may sound too formal in casual speech.Use 'partly' when you want to describe something that is only true in part. It’s appropriate in both spoken and written English, but avoid using it in overly formal contexts.Use 'somewhat' when you want to describe something that is not completely true but partially so. It's neutral, so it's suitable for both formal and informal contexts.
