Postponing visit, initially in broken English (8)
I believe the answer is:
shelving
'postponing' is the definition.
('shelve' can be a synonym of 'postpone')
'visit initially in broken english' is the wordplay.
'initially' indicates taking the first letters.
'in' is an insertion indicator.
'broken' is an anagram indicator.
The first letter of 'visit' is 'v'.
'english' with letters rearranged gives 'sheling'.
'v' placed within 'sheling' is 'SHELVING'.
(Other definitions for shelving that I've seen before include "Delaying" , "accommodation for books, perhaps" .)
