Have more than admired dress? Exposed on top (9)
I believe the answer is:
outnumber
'have more than admired' is the definition.
I can't tell whether this definition defines the answer.
'dress? exposed on top' is the wordplay.
'dress?' becomes 'number' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'exposed' becomes 'out' (to out someone is to expose them).
'on top' says to put letters next to each other (in a down clue, some letters go above others).
'number' after 'out' is 'OUTNUMBER'.
Can you help me to learn more?
(Other definitions for outnumber that I've seen before include "Exceed in total of persons" , "Have more (eg troops) than" , "Be in the majority" , "Exceed numerically" , "Be more numerous than" .)
