Fine number somewhat closer to fifty (5)
I believe the answer is:
dishy
'fine' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I can't see?
'number somewhat closer to fifty' is the wordplay.
'number' becomes 'd' (D is an example).
'somewhat' becomes 'ish' (eg 'amateurish' means somewhat amateur).
'closer to' suggests the final letters (the letter which ends or closes the word).
The final letter of 'fifty' is 'y'.
'd'+'ish'+'y'='DISHY'
Can you help me to learn more?
(Other definitions for dishy that I've seen before include "Good-looking (colloq.)" , "Fair" , "Attractive" , "Handsome" , "Gorgeous" .)
