Nope, a Lear is some form of jet (9)
I believe the answer is:
aeroplane
'jet' is the definition.
(thesaurus)
'nope a lear is some form' is the wordplay.
'is some' becomes 'a'.
'form' is an anagram indicator (a different form of the same letters).
'nope'+'lear'+'a'='nopeleara'
'nopeleara' is an anagram of 'AEROPLANE'.
'of' acts as a link.
(Other definitions for aeroplane that I've seen before include "Eg, jumbo jet" , "Flying craft" , "What taxis" , "crate?" , "Flying vehicle" .)
