An adolescent male dressed at last in rubber finding wealth (7)
I believe the answer is:
aladdin
'rubber finding wealth' is the definition.
'Aladdin' can be an answer for 'rubber' (Aladdin rubbed a magic lamp). I am not sure about the 'finding wealth' bit.
'an adolescent male dressed at last in' is the wordplay.
'an' becomes 'a'.
'adolescent male' becomes 'lad' (lad can mean a young boy).
'at last' suggests the final letters.
The last letter of 'dressed' is 'd'.
'a'+'lad'+'d'+'in'='ALADDIN'
Can you help me to learn more?
(Other definitions for aladdin that I've seen before include "Panto character with magic lamp (7)" , "Panto lamp rubber" , "Lad with a lamp" , "Pantomime set in China" , "pantomime role" .)
