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 cannot see how they can define each other.
'where in hospital you can' is the wordplay.
'PIT' is hidden in amongst the letters.
However, I'm unsure how the hidden word is indicated.
'get' acts as a 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" .)
