I occupy derelict chalet - is that right? (7)
I believe the answer is:
ethical
'that right?' is the definition.
(I've seen this in another clue)
'i occupy derelict chalet' is the wordplay.
'occupy' indicates putting letters inside (inserted letters occupy or enter the word).
'derelict' indicates an anagram (a derelict or broken spelling).
'chalet' with letters rearranged gives 'ethcal'.
'i' inserted within 'ethcal' is 'ETHICAL'.
'is' is the link.
(Other definitions for ethical that I've seen before include "Moral, honest" , "Conforming to accepted standards of behaviour" , "Morally right" , "Morally correct, honourable" , "In accordance with approved moral standards" .)
