Landing strip from which it’s impossible to take off (8)
I believe the answer is:
flypaper
'landing strip from which' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'impossible to take off' is the wordplay.
'impossible' becomes 'paper' (I can't justify this - if you can you should believe this answer much more).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'take off' becomes 'fly' (I've seen this in another clue).
'paper' put after 'fly' is 'FLYPAPER'.
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for flypaper that I've seen before include "Sticky trap for bluebottles etc" , "for hanging being used for killing" , "Sticky insect trap" , "one collecting insects" , "Sticky stuff to trap insects" .)
