Struck with small glove (7)
I believe the answer is:
smitten
'struck with' is the definition.
(thesaurus)
'small glove' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'glove' becomes 'mitten' (mitten is a kind of glove).
's'+'mitten'='SMITTEN'
(Other definitions for smitten that I've seen before include "Enchanted by mittens" , "Severely afflicted" , "Affected or struck by, disease or desire" , "Affected by something overwhelming" , "Captivated" .)
