We hear big fire may be here (5)
I believe the answer is:
grate
'fire may be here' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'we hear big' is the wordplay.
'we hear' shows a homophone (sound like).
'big' becomes 'great' (synonyms).
'great' sounds like 'GRATE'.
Can you help me to learn more?
(Other definitions for grate that I've seen before include "Make a harsh rasping sound" , "Fireplace recess; rasp" , "Reduce to small shreds" , "Grind, rasp" , "Rasp; shred" .)
