Inherited from Old East Slavic лъжь (lŭžĭ), from Proto-Slavic *lъžь. Cognate with Old Church Slavonic лъжь (lŭžĭ), Ukrainian лож f (lož), dialectal Belarusian лэш f (leš) (Old Belarusian лож (lož)), Old Czech lež f, Czech lež f, Slovak lož f, Old Polish łeż, Slovincian łäž f, Serbo-Croatian lȃž f, Slovene láž f (tonal orthography), lȅž f (tonal orthography). Has an exact reflex in Old English lyġe, English lie from Proto-Germanic *lugiz.
- Some Russians differentiate between ложь (ložʹ) and враньё (vranʹjó). A lie which is told to deceive someone is a ложь. Tall tales told without the malicious intention of deceiving others are враньё. In practice, however, both words can be used with the same meaning, враньё sounding informal and ложь sounding formal.
- врать (vratʹ)
