Part of gut last to enjoy settlement (6)
I believe the answer is:
colony
'settlement' is the definition.
(I know that settlement can be written as colony)
'part of gut last to enjoy' is the wordplay.
I cannot quite see how this works, but
'part' could be 'colon' (colon is a kind of part) and 'colon' is located in the answer.
A single letter 'y' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for colony that I've seen before include "Hive" , "Country under the political control of another and occupied by settlers" , "Group of organisms of the same type living together" , "Beavers' group" , "Group of animals of the same type living together" .)
