暂且 (zànqiě) is an adverb meaning 'for the time being' — it suggests a temporary, provisional arrangement that will likely change. It is more formal and literary than 暂时 (zànshí), which can also be an adjective ('temporary'). 姑且 (gūqiě) is similar but adds a sense of 'tentatively, as a concession'; 权 (quán) as an adverb is even more literary and rare in speech.
