Romantic couple not excited: back to being boring through trip (9)
I believe the answer is:
coleridge
'romantic' is the definition.
(Romantic poet Samuel Taylor Coleridge)
'back to being boring through trip' is the wordplay.
'back to' says to take the final letters.
'boring' means one lot of letters goes inside another (some letters must 'bore' a hole into other letters).
'through' becomes 'cole' (I can't explain this - if you can you should believe this answer much more).
'trip' becomes 'ride' (eg a trip in a car).
The final letter of 'being' is 'g'.
'cole'+'ride'='coleride'
'g' inserted within 'coleride' is 'COLERIDGE'.
'couple not excited' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for coleridge that I've seen before include "Samuel Taylor . . . . . . . . ., eminent poet" , "Exponent of art" , "Ancient Mariner poet" , "Kubla Khan poet" , "Samuel Taylor . . . . . . . . . who wrote 'The Ancient Mariner'" .)
