African rug — and a napkin — somewhere inside (7)
I believe the answer is:
ugandan
'african' is the definition.
(Ugandan is an example)
'rug and a napkin somewhere inside' is the wordplay.
'somewhere inside' indicates the answer is hidden within the clue.
'UGANDAN' can be found hidden inside 'rug and a napkin'.
(Other definitions for ugandan that I've seen before include "Eg, Kampala native" , "Idi Amin, for one" , "From Kampala or Entebbe?" , "Particular African" , "African national" .)
