Showing versatility, fitting into a seedy establishment (8)
I believe the answer is:
adaptive
'showing versatility fitting into a seedy establishment' is the definition.
I can't judge whether this defines the answer.
'fitting into a seedy establishment' is the wordplay.
'fitting' becomes 'apt' (both mean appropriate).
'into' means one lot of letters goes inside another.
'seedy establishment' becomes 'dive' (I've seen this in another clue).
'a'+'dive'='adive'
'apt' placed within 'adive' is 'ADAPTIVE'.
Can you help me to learn more?
(Other definitions for adaptive that I've seen before include "Pertaining to adjustment to new conditions" , "That may well change" , "Able to become adjusted to suit new conditions" , "likely to be suitable" .)
