Guide to a poetic area at Land's End (4)
I believe the answer is:
lead
'guide' is the definition.
(lead can mean to usher or guide)
'area at land's end' is the wordplay.
'area' becomes 'lea' (lea is a kind of area).
'at' is a charade indicator (letters next to each other).
'end' says to take the final letters.
The final letter of 'land' is 'd'.
'lea'+'d'='LEAD'
'to a poetic' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for lead that I've seen before include "Principal role in a play" , "Metal; clue" , "First news item" , "Go ahead; element" , "Heavy metal; star" .)
