Something to secure psalter that's falling apart? (7)
I believe the answer is:
stapler
'something to secure' is the definition.
I can't judge whether this defines the answer.
'psalter that's falling apart?' is the wordplay.
'that's falling apart?' indicates anagramming the letters.
'psalter' anagrammed gives 'STAPLER'.
Can you help me to learn more?
(Other definitions for stapler that I've seen before include "Item of office equipment" , "Paper-fastening device" , "Office fastener" , "Implement for inserting paper fasteners" , "It's used to attach leaves" .)
