Family label vase with identical wrapping (7)
I believe the answer is:
surname
'family label' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?
'vase with identical wrapping' is the wordplay.
'vase' becomes 'urn' (both can mean a container).
'with identical' becomes 'same' (similar in meaning. I am not sure about the 'with' bit.).
'wrapping' is an insertion indicator.
'urn' inserted inside 'same' is 'SURNAME'.
Can you help me to learn more?
(Other definitions for surname that I've seen before include "Something one gets from father" , "title inherited from parent" , "Family cognomen" , "Last appellation" , "Word by which a family is known" .)
