optionally omit "-zero" in multiples of 10 for brevity, if it does not cause ambiguity.  for example, if reading a string of numbers, we need to keep "-zero" to distinguish "90 9" from "99", or "10 4" from "14".  (the former is a problem in unfixed English, additionally ambiguous with "19 9".)

keeping "ten" as an isolated irregular but convenient synonym for one-ty-zero seems reasonable.

one-ty sounds similar to the old word twenty, but not the new word two-ty.
