Remove clip from one page, say (5)
I believe the answer is:
unpeg
'remove clip' is the definition.
(a peg is a kind of clip)
'one page say' is the wordplay.
'one' becomes 'un' (northern English dialect form of 'one').
'page' becomes 'p'.
'say' becomes 'eg'.
'un'+'p'+'eg'='UNPEG'
'from' is the link.
(Other definitions for unpeg that I've seen before include "Take down from the line" , "Detach" , "no longer freeze" , "free" , "Remove (clothes from a washing line)" .)
