West side of London? (3)
I believe the answer is:
ham
This could be a double definition.
'west side' is the first definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'london?' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for ham that I've seen before include "Thespian who overacts, informally" , "under twenty-eight [HIP]" , "Coarse" , "Meat of the hog" , "Overacting pig?" .)
