Stylish English worker welcoming support (7)
I believe the answer is:
elegant
'stylish' is the definition.
(both can mean fancy or ornate)
'english worker welcoming support' is the wordplay.
'english' becomes 'E' (abbreviation as in OED).
'worker' becomes 'ant' (worker is a type of ant).
'welcoming' is an insertion indicator (in sense of 'inviting in').
'support' becomes 'leg' (leg is a kind of support).
'e'+'ant'='eant'
'eant' placed around 'leg' is 'ELEGANT'.
(Other definitions for elegant that I've seen before include "Chic; smart" , "Gracefully stylish" , "A gentle way to be stylish" , "A gentle sort of stylish appearance" , "Fine" .)
