action, the pusdalyvis must be used instead (present active participle does not have this function): Atidarydama langą mergina grožėjosi tekančia saule. – While opening the window, the girl admired the sunrise. See "Adverbial participles" for further explanation. The third, a somewhat rarer, function is to explain (precise) another verb by indicating a secondary action of which the subject is the agent: Kaltinamasis prisipažįsta padaręs nusikaltimą ir labai dėl to gailisi. – The defendant confesses having committed the crime and sincerely regrets it. If the subject is not the agent expressed in the nominative case of a noun or a pronoun, an adverbial participle must be used instead.

In Lithuanian reflexive verbs can be transitive: susipinti plaukus – to plait one's hair [to oneself]. Passive voice present participles and the necessity participles can acquire degrees of comparison if their meaning allows it: mėgti (to like) → liked (favourite), mėgstamesnis (more liked), mėgstamiausias (most liked/favorite); būti (to be) → būtinas (necessary), būtinesnis (more necessary), būtiniausias (the most necessary). The necessity participles are used to describe something that has to be done: Įsidėmėtinos rašybos atvejis – A spelling case one has to pay special attention to. Abejotina, ar mums pavyks – It is to be doubted if we succeed. Mostly limited to official styles, but certain participles are actively used in colloquial speech as well, some of them being considered more adjectives than verbs: Jis suimtas už pasibaisėtiną elgesį su gyvūnais – He was arrested for an appalling behaviour with animals. (Pasibaisėtinas = one that has to be detested). Main passive participles mainly denote actions that have impact upon nouns they describe: statomas namas – a house that is being built, iškeltas klausimas – a question that has been raised, vykdysimas įsakymas – an order that will be obeyed. Future passive participles are rare in modern speech. Present passive participles very often have an active meaning, especially if the verb is intransitive, and are one of the terminology building tools: kuliamoji mašina
