Regret getting English can from attendants (7)
I believe the answer is:
retinue
'attendants' is the definition.
(I've seen this before)
'regret getting english can' is the wordplay.
'regret' becomes 'rue' (to rue something is to regret it).
'getting' means one lot of letters goes inside another.
'english' becomes 'e' (abbreviation).
'can' becomes 'tin' (both are metal containers).
'e'+'tin'='etin'
'rue' going around 'etin' is 'RETINUE'.
'from' is the link.
(Other definitions for retinue that I've seen before include "VIP's attendants" , "Body of attendants" , "Body of followers" , "Group of servants with important person" , "Body of aides" .)
