Is no garment superior to this one? (7)
I believe the answer is:
overall
'is no garment superior to this one?' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'superior to this one?' is the wordplay.
'superior to' becomes 'over' (I've seen this in another clue).
'this one?' becomes 'all' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'over'+'all'='OVERALL'
Can you help me to learn more?
(Other definitions for overall that I've seen before include "sweeping?" , "Dungarees" , "Taking everything into account" , "Taken as a whole" , "All round" .)
