Infatuated by small glove (7)
I believe the answer is:
smitten
'infatuated' is the definition.
(I know that infatuated can be written as smitten)
'by small glove' is the wordplay.
'by' says to put letters next to each other.
'small' becomes 's' (abbreviation - e.g. clothes size).
'glove' becomes 'mitten' (mitten is a kind of glove).
's' put next to 'mitten' is 'SMITTEN'.
(Other definitions for smitten that I've seen before include "Much affected; struck" , "Severely affected (by something)" , "Affected by something overwhelming" , "bowled over" , "Very much in love" .)
