Each week of 2017 we present an English idiom.
"to stick it out": to continue to the end of a situation that is difficult or unenjoyable (especially in AE); bis (zum Ende) durchhalten
Example 1: The secondment ends in two months. Surely you can stick it out until then.
Example 2: He wasn't feeling well but stuck it out until the trade show ended. As a result we acquired a new client who stopped by our stand an hour before closing.
