Sort of sentence in a workers' settlement (8)
I believe the answer is:
compound
'sort of sentence' is the definition.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for compound that I've seen before include "Chemical substance; enclosed space" , "Blended substance - enclosed area" , "A mix of ingredients" , "See 10" , "Kind of interest accumulating on capital plus interest" .)
