The following sentence seems incorrect to me, because the adjective timely is being used as an adverb:

Payments not received timely will be returned and additional interest will be due.

That said, does timely even have an adverbial form? Timelyly?

    I don't think there's an adverbial form based on time - we use the word promptly. Jan 22, 2013 at 18:15

    "Does timely even have an adverbial form? Timelyly?" Well ... it does now ...

    My spelling teacher would probably have said timely becomes timelily. Just as happy becomes happily and so on.

  • @GEdgar of course. Thanks for the clarification (that should have been obvious). I think we've collectively created a new adverb Jan 26, 2013 at 2:43

On time is surely the adverbial phrase that would be used in most cases. John Lawler would doubtless say that striving for a single related adverb (central though this usage would be in this case) is not a wise use of time.

  • I was pleasantly impressed to read all the great suggestions—promptly, timeously, punctually; even the original timely. But I think this one best captures the notion of a strict deadline for those payments. Thanks everyone. Jan 23, 2013 at 1:29

You could use "timeously". The word is often used in formal documents in Scotland, but is obscure in the rest of the Anglosphere.

  • It takes four syllables to say this, right? Jan 23, 2013 at 1:22

    @EricNelson: Yes, four syllables. But it takes six to say "in a timely manner" by my count. Jan 23, 2013 at 8:11
  • @EricNelson Actually it's three syllables. It's not that obscure, I've read it and heard it here in Australia. Oct 30, 2013 at 21:48

You can use timely as an adverb to mean "in time", though this is not so common.


I'd suggest:

Payments not received punctually will be returned...

  • Payments not received on time...
