Only about five find the answer (5)
I believe the answer is:
solve
'find the answer' is the definition.
(I've seen this in another clue)
'only about five' is the wordplay.
'only' becomes 'sole' (synonyms).
'about' indicates putting letters inside.
'five' becomes 'V' (Roman numeral).
'sole' going around 'v' is 'SOLVE'.
(Other definitions for solve that I've seen before include "Find an answer to (a problem)" , "Find the answer to a puzzle" , "Find the 3dn to a mystery" , "Find the answer or explanation" , "Work out (a clue)" .)
