How to address the head boy? (6)
I believe the answer is:
master
'head boy?' is the definition.
'master' can be an answer for 'head' (thesaurus). I am not sure about the 'boy?' bit.
'how to address the' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
The remaining letters 'maser' 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 master that I've seen before include "Maestro; teacher" , "Overcome; original film" , "controlling" , "The boss" , "Overcome; original copy" .)
