Work at arrangement to dismiss fine undervalued worker (7)
I believe the answer is:
doormat
'worker' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'work at arrangement to dismiss fine undervalued' is the wordplay.
I cannot quite see how this works, but
'work' could be 'do' (synonyms) and 'do' is found in the answer.
'at' is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for doormat that I've seen before include "Wipe feet on this before entering" , "Habitually humiliated person" , "sometimes trampled on by trainers" , "Drudge" , "Shoe wiper at entrance" .)
