When king has small questions (4)
I believe the answer is:
asks
'questions' is the definition.
(I've seen this before)
'when king has small' is the wordplay.
'when' becomes 'as'.
'king' becomes 'k'.
'has' means one lot of letters go next to another.
'small' becomes 's' (abbreviation - e.g. clothes size).
'as'+'k'+'s'='ASKS'
(Other definitions for asks that I've seen before include "Puts a question" , "Requests information about" , "Begs" , "Questions" , "Inquiries" .)
