Robinson sounds a bit like Caruso (6)
I believe the answer is:
crusoe
'caruso' is the definition.
Both the definition and answer are singular nouns.
Maybe there's a link between them I don't understand?
'robinson sounds a bit' is the wordplay.
I cannot quite see how this works, but
'bit' could be 'o' (resembles 0, a binary digit or bit) and 'o' is found in the answer.
The remaining letters 'cruse' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'like' acts as a link.
Can you help me to learn more?
(Other definitions for crusoe that I've seen before include "Daniel Defoe wrote ''Robinson . . . . . .''" , "Robinson . . . . . . was a famous fictional castaway" , "Daniel Defoe's hero" , "shipwrecked fellow" , "Robinson . . . . . . literary castaway" .)
