Familiar supporting feature of mug, plates etc (9)
I believe the answer is:
chinaware
'mug plates etc' is the definition.
I can't tell whether this defines the answer.
'familiar supporting feature' is the wordplay.
'familiar' becomes 'aware' (I can't explain this - if you can you should give a lot more credence to this answer).
'supporting' says to put letters next to each other (in a down clue, some letters go below others).
'feature' becomes 'chin' (facial feature).
'aware' put after 'chin' is 'CHINAWARE'.
'of' is the link.
Can you help me to learn more?
(Other definitions for chinaware that I've seen before include "what to put on table" , "Potty group" , "Ceramic articles" , "Dresden set" , "porcelain" .)
