Past, present and future (6)
I believe the answer is:
tenses
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">past present and future</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for tenses that I've seen before include "Tautens; verb forms" , "Becomes stretched or taut" , "Verb forms that indicate time" , "Verb forms indicating time" , "Future or past, say" .)
