Play C, E and G perhaps. Sound familiar? (6,1,5)
I believe the answer is:
strike a chord
'play c e and g perhaps sound familiar?' is the definition.
I can't tell whether this definition defines the answer.
'play c e and g' is the wordplay.
I cannot quite understand how this works, but
'play' could be 'chord' (chording is a kind of playing) and 'chord' is found in the answer.
'e' is within the answer.
'g' could be 'k' (synonyms) and 'k' is located in the answer.
The remaining letters 'stria' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for strike a chord that I've seen before include "Create an emotional response" , "Evoke a response" .)
