Andy's one to provide a non-committal answer (3,3,2)
I believe the answer is:
yes and no
'a non-committal answer' is the definition.
'yes and no' can be an answer for 'answer' (I have seen 'ambiguous answer' mean 'yes and no' so perhaps 'answer' could also mean 'yes and no'). I'm not certain of the 'a non-committal' bit.
'andy's one to provide' is the wordplay.
'to provide' indicates anagramming the letters.
'andys'+'one'='andysone'
'andysone' is an anagram of 'YES AND NO'.
Can you help me to learn more?
(Other definitions for yes and no that I've seen before include "To a certain degree" , "ambiguous answer" , "Partly" , "That's true, in part" , "Two in opposition" .)
