Shop initially with two articles to wrap up (6)
I believe the answer is:
swathe
'wrap up' is the definition.
(thesaurus)
'shop initially with two articles' is the wordplay.
'initially' indicates taking the first letters.
'with' becomes 'w' (abbreviation**).
'two articles' becomes 'athe' (article meaning part of speech: the, a etc.).
The initial letter of 'shop' is 's'.
's'+'w'+'athe'='SWATHE'
'to' is the link.
(Other definitions for swathe that I've seen before include "A broad strip as of cut grass" , "considerable cut" , "Bandage completely - band of mown grass" , "Broad strip or area; wrap in fabric" , "An enveloping bandage" .)
