Article dons removed pops (6)
I believe the answer is:
father
'pops' is the definition.
(I've seen this before)
'article dons removed' is the wordplay.
'article' becomes 'the' (the definite article).
'dons' means one lot of letters goes inside another (don can mean to wear or be covered in).
'removed' becomes 'far' (synonyms).
'the' put within 'far' is 'FATHER'.
(Other definitions for father that I've seen before include "PA" , "Relative and priest" , "and 13: Jolly gift-deliverer" , "relation" , "Old man" .)
