Greedy fellow's house at Gateshead (3)
I believe the answer is:
hog
'greedy fellow's house at gateshead' is the definition.
I can't judge whether this defines the answer.
'house at gateshead' is the wordplay.
'house' becomes 'ho' (abbreviation for house).
'at' means one lot of letters go next to another.
'gateshead' becomes 'g' (head letter of 'gates').
'ho'+'g'='HOG'
Can you help me to learn more?
(Other definitions for hog that I've seen before include "Pig, who holds the road perhaps" , "source of meat" , "Take greedily" , "Selfishly keep" , "A male pig or a greedy person" .)
