the nominative one. As in the case of noun paradigms, there were *i̯o- (fem. *i̯ā-) and *ii̯o- (fem. *ē-) stem variants next to the *o-stem adjectives. Feminine gender forms were constructed with the *ā-stem while the feminine forms with the *i̯ā-stem (sing. nom. *-ī) were constructed with the *u-stem adjectives. The feminine gender of the masculine and neuter genders for the *i-stem probably resulted with *i̯ā- or *ē-stems. However, the reconstruction of the later is difficult as the *i-stem adjectives in the current Baltic languages were poorly preserved. *o-stem, *ā-stem adjectives *labas 'good' *u-stem, *i̯ā-stem adjectives *platus 'wide' *i-stem, *ē-stem adjectives *aru̯is 'suitable' Verbs The reconstruction of the verb of Proto-Baltic is mostly based on the collected data on the Eastern Baltic languages, as the verb system in Old Prussian is poorly attested. The reconstructed verb system is attributed to the later stages of linguistic development. Unlike other parts of speech, the verb of Proto-Baltic experienced a lot of changes—the grammatical mood, tense and voice systems that came from PIE changed. For instance, from the former Proto-Indo-European tenses—the present, the aorist, the perfect—only the present was preserved by Proto-Baltic in addition to the sigmatic future, which by some researchers is considered to be an inheritance from late PIE. In PIE there were four moods: indicative, subjunctive, optative and imperative. In Proto-Baltic, indicative remained but subjunctive was changed by the newly formed conditional mood. Meanwhile, imperative gained forms from optative. PIE also had two verb voices – active and mediopassive. The latter was changed with reflexive verbs in Proto-Baltic. New types of verb form (the analytical perfect and the pluperfect) and the analytical passive voice were created. The most archaic trait of Proto-Baltic is the retained athematic conjugation.Bičovský, J. (2009).

In the first and second person forms, Proto-Baltic had preserved the three numbers from PIE (singular, dual and plural), while in third person, number was not distinguished. The verb of the Proto-Baltic had three basic stems, i.e. the stems of the present tense, past tense and the infinitive. All forms of the verb were based on those stems. For example, the stems of the verb 'to carry' were *neša-, *nešē-, *neš-; the stems of the verb 'to sit' were *sēdi-, *sēdējā-, *sēdē-. Compared to Lith. nẽša 'he carrys', nẽšė 'he carried',
