Assume nothing in such a colony? (6)
I believe the answer is:
nudist
'colony?' is the definition.
I know that 'colony' relates to this answer. I also know that both the answer and definition are singular nouns
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for nudist that I've seen before include "S/he prefers to be naked" , "One not covered" , "One going naked" , "One who disapproves of clothes" , "one whose barely seen" .)
