Match extinguished, perhaps, in front of grate? Be clear (2,7,6)
I believe the answer is:
go without saying
'be clear' is the definition.
(I've seen this before)
'match extinguished perhaps in front of grate?' is the wordplay.
I cannot quite see how this works, but
'match' could be 'gowith' (I've seen this before) and 'gowith' is located in the answer.
'extinguished' could be 'out' (synonyms) and 'out' is found in the answer.
'perhaps' could be 'say' (both can mean 'for example') and 'say' is found within the answer.
'in' is found in the answer.
A single letter 'g' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for go without saying that I've seen before include "Leave unannounced" , "self-evident" , "but appear obvious" , "Stand to reason" , "clear" .)
