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 tell whether this defines the answer.
'fitting into a seedy establishment' is the wordplay.
'fitting' becomes 'apt' (both mean appropriate).
'into' indicates putting letters inside.
'seedy establishment' becomes 'dive' (I've seen this in another clue).
'a'+'dive'='adive'
'apt' put into '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" .)
