Travel from airport with engine loose (13)
I believe the answer is:
'travel' is the definition.
(peregrination is wandering around)
'airport with engine loose' is the wordplay.
'with' says to put letters next to each other.
'loose' is an anagram indicator (letters are loosened from their original positions).
'airport' put after 'engine' is 'engineairport'.
'engineairport' anagrammed gives 'PEREGRINATION'.
'from' acts as a link.
(Other definitions for peregrination that I've seen before include "Long meandering journey" , "Travelling about" , "Globe-trotting" , "wandering" .)
