On one occasion (4)

Ross

I believe the answer is:

once

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">on one occasion</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is the entire clue.<br/ ></span>

(Other definitions for once that I've seen before include "Just as a single occurrence" , "At some former time" , "On a single (or past) occasion" , "In the old days" , "'... bitten, twice shy'" .)

I've seen this clue in The Mirror.
