Ring tuner about paying another visit (9)
I believe the answer is:
returning
'paying another visit' is the definition.
'returning' can be an answer for 'paying' (returning is a kind of paying). I'm not certain of the 'another visit' bit.
'ring tuner about' is the wordplay.
'about' is an anagram indicator.
'ring'+'tuner'='ringtuner'
'ringtuner' anagrammed gives 'RETURNING'.
Can you help me to learn more?
(Other definitions for returning that I've seen before include "On the way back" , "Coming back" , "Yielding" , "Going or taking back" .)
