The part of a toaster that dries (4)
I believe the answer is:
oast
'the part of a toaster that dries' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'the part of a toaster that' is the wordplay.
'the part of' says the answer is hidden in the clue.
'OAST' is hidden in the letters of 'toaster that'.
Can you help me to learn more?
(Other definitions for oast that I've seen before include "Kiln for drying hops or malt" , "Oven for hops" , "Where to cook" , "Drying house" , "Hop-drier" .)
