Book for a pound, with hesitation (5)
I believe the answer is:
album
'book' is the definition.
(album is a kind of book)
'a pound with hesitation' is the wordplay.
'pound' becomes 'lb' (abbreviation for the unit of weight).
'with' says to put letters next to each other.
'hesitation' becomes 'um' (sound made when hesitating).
'a'+'lb'+'um'='ALBUM'
'for' is the link.
(Other definitions for album that I've seen before include "CD or photo book" , "Blank book for mounting photos, stamps etc" , "Record with multiple tracks" , "A music record or a book of photos" , "series of tracks" .)
