Cockney's hurt by stone in nasty place (6)
I believe the answer is:
armpit
'nasty place' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'cockney's hurt by stone' is the wordplay.
'cockney's hurt' becomes ''arm' ('harm' - synonyms - said with a cockney accent, dropping the 'H').
'by' is a charade indicator (letters next to each other).
'stone' becomes 'pit' (synonyms).
'arm'+'pit'='ARMPIT'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for armpit that I've seen before include "A sort of hollow" , "(In anato my) the axilla" , "Hairy hollow" , "Depression under an upper limb" , "Bodily hollow" .)
