Arrive late for these bonfires (5)
I believe the answer is:
pyres
'arrive late for these bonfires' is the definition.
The definition suggests an adverb but the answer is not.
'arrive late for these bonfires' is the wordplay.
'arrive' becomes 'py' (I can't explain this - if you can you should give a lot more credence to this answer).
'late' says to take the final letters (I've seen 'latest of' mean this).
The final letters of 'for these bonfires' are 'res'.
'py'+'res'='PYRES'
Can you help me to learn more?
(Other definitions for pyres that I've seen before include "Funeral fires" , "Funeral piles" .)
