难免 (nánmiǎn) means "to be unavoidable" or "inevitable" and is most commonly placed before a verb, often an auxiliary verb such as 会 or 要. It can only be used to introduce an inevitable situation that is characterized by negative features. One cannot use 难免 to talk of a positive inevitability such as "you will inevitably have a good time".
