He took the wrong course and got shipwrecked (6)
I believe the answer is:
crusoe
'he took' is the definition.
The definition suggests a singular noun which matches the answer.
'wrong course and got shipwrecked' is the wordplay.
'course' anagrams to 'CRUSOE'.
But, I'm unsure how the anagram is indicated.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for crusoe that I've seen before include "Abandoned" , "See 9" , "Daniel Defoe's castaway" , "Robinson . . . . . . was a famous fictional castaway" , "Defoe's hero derived" .)
