Desiccant found in metal case (4)
I believe the answer is:
talc
'desiccant' is the definition.
The answer and definition can be both substances as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'in metal case' is the wordplay.
'in' says the answer is hidden in the clue.
'TALC' can be found hidden inside 'metal case'.
'found' acts as a link.
Can you help me to learn more?
(Other definitions for talc that I've seen before include "Powdered mineral" , "Softest substance in Mohs scale of hardness" , "Perfumed drying powder" , "Powder used as toiletry" , "White powder for the bathroom" .)
