Ring and glove given to man left out (7)
I believe the answer is:
omitted
'left out' is the definition.
(to omit something is to leave it out)
'ring and glove given to man' is the wordplay.
'ring' becomes 'O' (O is the shape of a ring).
'and' says to put letters next to each other.
'glove' becomes 'mitt' (synonyms).
'given to' means one lot of letters go next to another.
'man' becomes 'ed' (short for Edward).
'o'+'mitt'+'ed'='OMITTED'
(Other definitions for omitted that I've seen before include "not mentioned" , "Hairdressing" , "Cardigan boy" , "Left out, probably forgot" , "Musical aptitude" .)
