Where fire is laid, no thanks from him (7)
I believe the answer is:
ingrate
'where fire is laid no thanks from him' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'from him' is the wordplay.
'from' becomes 'in' (I've seen this in other clues).
'him' becomes 'grate' (I can't explain this - if you can you should believe this answer much more).
'in'+'grate'='INGRATE'
Can you help me to learn more?
(Other definitions for ingrate that I've seen before include "Thankless sort" , "Thankless person from Tangier" , "one showing no appreciation" , "He doesn't appreciate" , "Thankless type" .)
