Shipwrecked heroine that may be found in bed (5)
I believe the answer is:
viola
This could be a double definition.
'shipwrecked heroine' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'bed' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'that may be found in' is the link.
Can you help me to learn more?
(Other definitions for viola that I've seen before include "Tenor fiddle - plant" , "Sebastian's sister" , "part of Shakespeare" , "Large fiddle" , "Instrument slightly larger than violin and of lower pitch" .)
