Like every single person (5)
I believe the answer is:
unwed
'single person' is the definition.
'unwed' can be an answer for 'single' (I've seen this before). I'm not certain of the 'person' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for unwed that I've seen before include "Without benefit of clergy?" , "Not married" , "Single" , "Divorced" .)
