Too easy to smuggle a chapter into computer record (6)
I believe the answer is:
'too easy' is the definition.
(facile can mean too easy or effortless)
'to smuggle a chapter into computer record' is the wordplay.
'to smuggle' means one lot of letters goes inside another (smuggle can mean to secretly carry).
'chapter' becomes 'c' (abbreviation).
'into' indicates putting letters inside.
'computer record' becomes 'file' (digital file).
'c' going into 'file' is 'fcile'.
'a' placed inside 'fcile' is 'FACILE'.
(Other definitions for facile that I've seen before include "Easily achieved but of little value" , "Lacking depth, argument say" , "Smooth" , "Lacking depth, glibly superficial" , "Effortless, easy" .)
