姑且【gūqiě】

姑且 accepts something for now while leaving room to change your mind: "for the time being", "let's just". It goes before the verb, and the sentence often implies "though I have my doubts" or "until something better turns up".

姑且不论: setting a point aside

In an argument, 姑且不论 or 姑且不谈 puts one issue to one side so the writer can press another.

姑且称之为

姑且称之为, "let's call it X for now", names something that has no settled name yet.

姑且 or 暂且

暂且 is about time: "for the moment, until later". 姑且 adds reluctance – you're accepting something you aren't fully happy with.

Position

姑且 goes before the verb, after the subject, never at the end where English puts "for now".
