Didn't tell the truth (4)
I believe the answer is:
lied
'didn't tell the truth' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lied that I've seen before include "German romantic recital piece" , "Song; fibbed" , "Romantic song told a story" , "refused to admit it" , "untrue" .)
