Attendants English can put in French street (7)
I believe the answer is:
retinue
'attendants' is the definition.
(thesaurus)
'english can put in french street' is the wordplay.
'english' becomes 'e' (abbreviation).
'can' becomes 'tin' ('tin' can be a synonym of 'can').
'put in' is an insertion indicator.
'french street' becomes 'rue' (French for street or road).
'e'+'tin'='etin'
'etin' inserted within 'rue' is 'RETINUE'.
(Other definitions for retinue that I've seen before include "Cortege" , "Body of aides" , "Body of retainers" , "Group attending a person" , "Group of servants with important person" .)
