Where, in hospital, you can get a mineral (3)
I believe the answer is:
pit
'a mineral' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'where in hospital you can' is the wordplay.
'PIT' is hidden in amongst the letters.
But, I am not sure how the hidden word is indicated.
'get' is the link.
Can you help me to learn more?
(Other definitions for pit that I've seen before include "Take stone" , "Mine; fruit-stone" , "See 9" , "where orchestra plays" , "Mining hole" .)
