Fellow in basic accommodation possibly mined gold in ancient city on borders of Thrace (10)
I believe the answer is:
troglodyte
'fellow in basic accommodation' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'mined gold in ancient city on borders of thrace' is the wordplay.
'mined' indicates an anagram.
'in' means one lot of letters goes inside another.
'ancient city' becomes 'troy' (Troy was an ancient city).
'on' is a charade indicator (letters next to each other).
'borders of' means to remove the middle letters.
'thrace' with its centre removed is 'te'.
'gold' anagrammed gives 'glod'.
'glod' going inside 'troy' is 'troglody'.
'troglody'+'te'='TROGLODYTE'
'possibly' is the link.
Can you help me to learn more?
(Other definitions for troglodyte that I've seen before include "Introvert" , "Cave-dweller" , "Recluse" , "low-lifer" , "Cave dweller" .)
