What could be alight on sixth of November! (7)
I believe the answer is:
bonfire
'what could' is the definition.
I can't tell whether this defines the answer.
'alight on sixth of november' is the wordplay.
'alight' becomes 'on fire' (synonyms).
'on' says to put letters next to each other.
'sixth of november' becomes 'b' (6th letter of 'november').
'onfire' after 'b' is 'BONFIRE'.
'be' acts as a link.
Can you help me to learn more?
(Other definitions for bonfire that I've seen before include "lit up in the garden" , "The - of the Vanities (Tom Wolfe)" , "Large outdoor fire" , "Source of blazing" , "Large outdoor blaze" .)
