Told untruths (4)
I believe the answer is:
lied
'told untruths' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for lied that I've seen before include "was responsible for terminological inexactitude" , "German romantic recital piece" , "Was economical with the truth" , "Stated falsely" , "German air" .)
