Individually produced in hotel with servant called (8)
I believe the answer is:
handmade
'called' is the definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I don't see?
'individually produced in hotel with servant' is the wordplay.
I cannot really see how this works, but
'produced' could be 'made' ('make' can be a synonym of 'produce') and 'made' is located in the answer.
'hotel' could be 'h' (phonetic alphabet: alpha, bravo, charlie etc.) and 'h' is located in the answer.
'with' could be 'and' and 'and' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for handmade that I've seen before include "E.g. like samplers" , "Personally developed" , "no machine involved" , "Bespoke" , "Not generated by machine" .)
