An overlapping Riley Riddle

Question

My attempt at a Riley Riddle:

My prefix is a limit.

My suffix is quite unlit.

My infix shows what's done--

but I'm afraid I don't have one.

What am I?

This is my first puzzle, so if anyone has any suggestions please let me know! — Carl Schildkraut, Apr 14 '18 at 18:25
Could you please add a hint?? Is it an everyday object or something which we have to bury our heads in Google to know the word? Is it a common word or a proper noun?? Thank you! :) — Rapiddagger, May 22 '18 at 15:26
@KarisYuen It is a word most people should know (not a proper noun), but isn't in particularly common use. It is a noun, but an idea rather than an object. — Carl Schildkraut, May 22 '18 at 22:57

That's an interesting answer! Unfortunately, as it doesn't fit the infix clue, it's not correct. – Carl Schildkraut Apr 14 '18 at 18:25
