An unusual pink piece of tableware (6)
I believe the answer is:
napkin
'tableware' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'an unusual pink piece' is the wordplay.
'unusual' indicates an anagram.
'piece' is an anagram indicator (I've seen 'pieces' mean this (the same pieces in a new order)).
'an' with letters rearranged gives 'na'.
'pink' is an anagram of 'pkin'.
'na'+'pkin'='NAPKIN'
'of' is the link.
Can you help me to learn more?
(Other definitions for napkin that I've seen before include "Cloth to stop, eg, gravy" , "piece of material giving consumer protection" , "Small piece of table linen" , "Protective cloth square donned during meals" , "Cloth square worn while eating" .)
