Fibbed (4)
I believe the answer is:
lied
'fibbed' is the definition.
(fib can mean to tell a lie)
This is all the clue.
(Other definitions for lied that I've seen before include "Told tale" , "was responsible for terminological inexactitude" , "gave a false impression" , "Romantic song told a story" , "German romantic recital piece" .)
