Usage Note
Certain has two very distinct uses depending on position: placed after the noun it means 'certain' or 'sure' (une victoire certaine, a certain victory), while placed before the noun it acts as a determiner meaning 'some' or 'a particular' (un certain temps, a certain amount of time). The adverb certainement (certainly) and the noun certitude are common derivatives.
Examples
"Il faut un certain temps pour apprendre."
