Can it fix broken plates? (6)

I believe the answer is:

staple

I'm a little stuck... Click here to teach me more about this clue!

'can it fix' is the definition.
I can't judge whether this definition defines the answer.

'broken plates?' is the wordplay.
'broken' is an anagram indicator.
'plates' with letters rearranged gives 'STAPLE'.

Can you help me to learn more?

(Other definitions for staple that I've seen before include "Fastener - principal" , "office item" , "Secure" , "Short U-shaped paper fastener" , "Principle - metal fastener" .)
