On account of tenor, a king in church gets the biscuit (7)
I believe the answer is:
oatcake
'the biscuit' is the definition.
(I've seen this before)
'on account of tenor a king in church' is the wordplay.
'on account of' becomes 'oa' (I can't explain this - if you can you should believe this answer much more).
'tenor' becomes 't'.
'king' becomes 'K' (abbreviation for king in chess).
'in' means one lot of letters goes inside another.
'church' becomes 'CE' (abbreviation for Church of England).
'a'+'k'='ak'
'ak' inserted inside 'ce' is 'cake'.
'oa'+'t'+'cake'='OATCAKE'
'gets' is the link.
Can you help me to learn more?
(Other definitions for oatcake that I've seen before include "Traditional Scottish biscuit" , "Traditional Scots biscuit" , "Savoury biscuit" , "Variety of biscuit" , "Scots biscuit-like food" .)
