nèšti 'to carry'; sė́di 'he sits', sėdė́jo 'he sat', sėdė́ti 'to sit'. Conjugation CH. Stang identifies the following conjugations of verbs in the present tense: athematic, thematic (*o-stem verbs) and semi-thematic (*i-stem and *ā-stem verbs). The future tense was formed using the *-s- / -*si- suffix attached to the infinitive stem, and because of the *-si- suffix, all future tense verbs were conjugated with the *i-stem. The past tense had *ā- and *ē-stems. With a few exceptions (1st sg. conditional *rinkti̯ā 'I would gather', 2nd sg. imperative *renkais 'gather!'), all verb endings were borrowed from the present tense. Infinitive In Proto-Baltic the infinitive was created with suffixes *-tei, *-tēi, *-ti: *eitei, *-tēi, *-ti 'go', *darītei, *-tēi, *-ti 'do'. The infinitive comes from the singular nominal of the word stem ti in its dative (*mirtei 'for death') and locative (*mirtēi 'in death'; consonant stem —*darānti 'in doing' (active participle, masculine–neuter) form. In Lithuanian, the relationship between the infinitive and dative can sometimes be observed to this day (e. g., kėdė yra sėdėti / sėdėjimui 'the chair is for sitting', ne metas liūdėti / liūdėjimui 'no time for sadness'). Supine In Proto-Baltic the supine was created with suffixes *-tun < PIE *-tum: *eitun, *darītun. This verb form is unconjugated and was used together with the verbs of movement to express the circumstances of a goal or an intention. The supine comes from the singular nominal of the word stem tu in its accusative form (*leitun 'rain'). The connection can be observed in the existing dialects of the current Baltic languages and is considered to be inherited from PIE as the supine can be found in other Indo-European languages as well. Aspect Aspect (e. g., imperfective aspect 'I was gathering' vs. perfective aspect 'I had gathered') might have been unusual to Proto-Baltic, as aorist tense, which were used to express a perfective aspect of a process in contrast to the present tense used to express the imperfective aspect, fell out of use. Participle Proto-Baltic had active and passive voice participles. Traditionally, it is believed that active voice participles already existed in PIE. Participles were modified in case the same way as the nominals. The vocative case probably coincided with the nominative one. The participle had three genders (masculine, feminine and neuter), numbers (singular, dual, plural) and tenses (present, future, past). Active participles were used to express a specific trait of an object that
