A woman from Cape Horn? (8)
I believe the answer is:
chaperon
'a woman' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'from cape horn?' is the wordplay.
'from' is an anagram indicator (the anagram comes from the same letters).
'cape'+'horn'='capehorn'
'capehorn' with letters rearranged gives 'CHAPERON'.
Can you help me to learn more?
(Other definitions for chaperon that I've seen before include "Accompany and look after" , "Girl minder from Cape Horn" , "One accompanies the vulnerable" , "One accompanies and looks after another person or group" , "One who accompanies and supervises" .)
