Scrapped lunch to take north-eastern link to the continent (7)
I believe the answer is:
chunnel
'link to the continent' is the definition.
I can't tell whether this definition defines the answer.
'scrapped lunch to take north-eastern' is the wordplay.
'scrapped' indicates anagramming the letters.
'to take' means one lot of letters goes inside another (inserted letters are taken in).
'north eastern' becomes 'NE' (abbreviation).
'lunch' is an anagram of 'chunl'.
'chunl' enclosing 'ne' is 'CHUNNEL'.
Can you help me to learn more?
(Other definitions for chunnel that I've seen before include "Railway passage between England and France" , "Anglo-French link" , "Kent/Pas-de-Calais link" .)
