The case for giving credit to a tea blender (5)
I believe the answer is:
crate
'the case' is the definition.
(both can mean a container)
'giving credit to a tea blender' is the wordplay.
'giving' means one lot of letters go next to another.
'credit' becomes 'cr' (abbreviation).
'to a tea blender' becomes 'ate' (I can't explain this - if you can you should give a lot more credence to this answer).
'cr' put next to 'ate' is 'CRATE'.
'for' is the link.
Can you help me to learn more?
(Other definitions for crate that I've seen before include "Box for shipping" , "Wooden box" , "Old car" , "Old soldiers might be found in this" , "Clapped-out vehicle" .)
