Foreign articles on sport seen as pants, perhaps (9)
I believe the answer is:
underwear
'pants perhaps' is the definition.
(I know that underpants is a type of underwear)
'foreign articles on sport' is the wordplay.
'foreign articles' becomes 'under'.
'on' says to put letters next to each other.
'sport' becomes 'wear' (sport can mean to wear or display on one's person).
'under'+'wear'='UNDERWEAR'
'seen as' is the link.
(Other definitions for underwear that I've seen before include "Garments worn beneath other clothes" , "Smalls or scanties, collectively" , "what lies beneath that uniform!" , "Lingerie" , "Smalls,shorts,lingerie etc" .)
