Bachelor inhabiting lock-up can type (7)
I believe the answer is:
garbage
'type' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'bachelor inhabiting lock-up' is the wordplay.
'bachelor' becomes 'B' (abbreviation e.g. BA=Bachelor of Arts).
'inhabiting' indicates putting letters inside (I've seen this in other clues).
'lock-up' becomes 'garage'.
'b' inserted into 'garage' is 'GARBAGE'.
'can' is the link.
Can you help me to learn more?
(Other definitions for garbage that I've seen before include "Brag about age? - that's rubbish" , "US rubbish" , "Nonsense!" , "Refuse - a beggar (anag)" , "hot air" .)
