That place holds a patient, ultimately? (7)
I believe the answer is:
theatre
'that place holds a patient ultimately?' is the definition.
I can't judge whether this definition defines the answer.
'that place holds a patient ultimately?' is the wordplay.
'that place' becomes 'there' (as opposed to 'here' meaning this place).
'holds' indicates putting letters inside.
'ultimately?' suggests the final letters (I've seen 'ultimately' mean this).
The final letter of 'patient' is 't'.
'a'+'t'='at'
'there' enclosing 'at' is 'THEATRE'.
Can you help me to learn more?
(Other definitions for theatre that I've seen before include "Space for drama" , "Art of writing and producing plays" , "Place for dramatic performances" , "eg The Globe" , "Scene of plays" .)
