Popular passing fancy to cause glaze to crack? (5)
I believe the answer is:
craze
'popular passing fancy' is the definition.
'craze' can be an answer for 'fancy' (thesaurus). I am not sure about the 'popular passing' bit.
'glaze to crack?' is the wordplay.
'glaze' becomes 'raze' (I can't explain this - if you can you should believe this answer much more).
'to' means one lot of letters go next to another (I've seen this in other clues).
'crack?' becomes 'C' (crack is a kind of C).
'raze' after 'c' is 'CRAZE'.
'to cause' acts as a link.
Can you help me to learn more?
(Other definitions for craze that I've seen before include "Mania" , "passing fashion" , "Sudden widespread enthusiasm (for something)" , "Fad, short-lived enthusiasm" , "Short-lived fashion" .)
