to modern Slavonic languages, each and every Lithuanian verb, in spite of its aspect, has all tenses and forms described in previous chapters of this article. Nevertheless, certain very general rules can be laid down to detect the aspect of a verb in Lithuanian. The imperfective aspect of a verb means the continuity of an action or a repetitiveness of a completed action. The imperfective aspect can sometimes be implied by: The absence of a prefix for certain verbs: dìrbti – to be working, šaũkti – to be shouting, krìsti – to be falling. The presence of a suffix (except for -er(ė)ti, -el(ė)ti) combined with the absence of a prefix for certain verbs: maldáuti – to be begging, mė́tyti – to be throwing [multiple times], šokinė́ti – to be jumping [constantly, multiple times]. The impossibility for certain verbs to be used without a prefix: užgaulióti – to be bullying, pãsakoti – to be telling a story. The complete or partial change of meaning for certain prefixed verbs: priklausýti – to be in possession (from klausýti – to listen), pakę̃sti – to tolerate (from kę̃sti – to suffer), atsidúoti – to be stinking (from dúoti – to give). For some prefixed verbs that merely indicate the ability to do something: panèšti – to be able to carry, nusėdė́ti – to be able to sit. The perfective aspect of a verb means the completeness of an action. The perfective aspect can sometimes be implied by: The presence of a prefix for certain verbs: padìrbti – to work for a certain amount of time, pašaũkti – to call, nukrìsti – to fall. There are very few perfective prefixed verbs that would distinguish themselves from their imperfective unprefixed counterparts only by their perfective meaning, since any prefix almost always has a semantical nuance. The presence of the suffix -er(ė)ti or -el(ė)ti: dìrsterėti – to take a glimpse, kúoktelėti – to become insane. In other cases the aspect is contextual. This might sometimes be implied by: The absence of a suffix and a prefix for certain verbs: – mèsti – to throw: Vakar mečiau darbą – I quit my job yesterday. (perfective) Visas senas knygas jis metė į šiukšlių dėžę – He was throwing all the old books to the trash bin. (imperfective) – grį̃žti – to come back: Grįžęs namo, virtuvėje rasi sriubos. – Having come back home, you’ll find some soup in the
