Regretting our name being appropriated by China (8)
I believe the answer is:
mourning
'regretting' is the definition.
The definition and answer can be both to do with human feelings as well as being present participle verbs.
Maybe you can see an association between them that I can't see?
'our name being appropriated by china' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'being appropriated by' indicates putting letters inside (I've seen this in other clues).
'china' becomes 'ming' (Chinese porcelain from the Ming dynasty).
'our'+'n'='ourn'
'ourn' going into 'ming' is 'MOURNING'.
Can you help me to learn more?
(Other definitions for mourning that I've seen before include "Sorrowing" , "Grieving" , "Feeling loss" , "wearing black" , "Black clothing" .)
