Short form (12)
I believe the answer is:
abbreviation
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">short form</span>' is the definition.<br/ ><span class="explanation-format__explanation">(abbreviation is a kind of form; 'short' suggests an abbreviation)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for abbreviation that I've seen before include "A short word" , "eg, may be one" , "BA, for example" , "plane, for example?" , "EU, for example" .)
