Popular attempt to get round limit (6)
I believe the answer is:
trendy
'popular' is the definition.
(thesaurus)
'attempt to get round limit' is the wordplay.
'attempt' becomes 'try' (synonyms).
'to get round' means one lot of letters goes inside another.
'limit' becomes 'end' (I've seen this in another clue).
'try' placed around 'end' is 'TRENDY'.
(Other definitions for trendy that I've seen before include "Fashionable, in style" , "Consciously fashionable" , "Informally in the latest fashion" , "In accordance with the latest fad" , "Chic (colloq.)" .)
