7. Slavic historical morphology: verbal system

7.1. PIE verbal dimensions

Post-Anatolian Proto-Indo-European had the following formally expressed verbal dimensions: aspect, tense–mood, voice, person–number (cf. Rix 1992: 190–194).

While Balto-Slavic preserve many of the verbal forms, the verbal system itself was restructured. Among the most important restructurings of Balto-Slavic and Slavic are the following:

Of the PIE perfect forms, only a single one, PIE pf.1sg *‍u̯ói̯d‑h₂а + *‍-i survives as OCS vědě ‘I know’, repurposed as a present.

All items of the person–number category are preserved in Balto-Slavic.

For the historical background of the Slavic aspects see Andersen (2009b).

7.2. The new imperfect

The inherited aorist and imperfect categories merged in Slavic as the aorist. However, at some pre-stage of Slavic a new imperfect category was created, expressed morphologically by a chain of suffixes: PS interfix *‍‑ē/∅‑, progressive ‑i̯ā‑, past *‍‑x/š‑, interfix *‍‑e/a‑ (the thematic vowel), person–number ending (Andersen 2013: 30–32).

It is likely that the interfix *‍‑ē‑ is identical with the Baltic past suffix *‍‑ē‑, e.g. Lith. pst.3ps něšė (inf nèšti ‘carry’), Lith. pst.3ps prãšė (inf prašýti ‘ask’).

The progressive suffix PS *‍‑i̯ā‑ is probably identical with the suffix *‍‑(i̯)ā‑ (CS *‍‑(j)a‑) used to derive imperfective verbs from perfective verbs (see 6.7).

The Common Slavic imperfect is preserved in OCS, Bulgarian, Macedonian, some varieties of BCMS, Upper Sorbian and Polabian.

7.4. Infinite forms

Participles: The PIE participial formations are generally well preserved in CS and OCS. Table 47 shows the correspondences between the OCS and PIE participles (OCS nes-ti ‘carry’, prs nes-ǫ; OCS ję-ti ‘take’, prs jĭm-ǫ).

Table 47: The participles of OCS and their PIE sources.
stem nom.sg.m nom.sg.f PIE base
prs.act.ptcp nes-ǫšt- nes-y nes-ǫšt-i prs.act.ptcp *‍-ont-
prs.pass.ptcp nes-om- nes-om-ŭ nes-om-a probably prs.pass.ptcp *‍-mh₁no-
pst.act.ptcp I nes-ŭš- nes-ŭ nes-ŭš-i pf.act.ptcp *‍-u̯ōs, *‍-u̯ot-, *‍-us-
pst.act.ptcp II nes-l- nes-l-ŭ nes-l-a adjective formation in *‍-lo-
pst.pass.ptcp nes-en- nes-en-ŭ nes-en-a adjective formation in *‍-no-
ję-t- ję-t-ŭ ję-t-a to-participle

The present passive participle OCS nesomŭ is identical with Lith. nẽšamas and is likely to reflect PIE *‍-mh₁no-, also found in Gk. ‑μενο‑ etc. (Nowak 2017).

For the past passive participle cf. Goth. bundans.

The most important formal change is that – outside the masculine–neutre nominative singular – the stems of the present and past active participles are based on the original feminine allomorph: PIE prs.act.ptcp *‍‑ont‑i̯‑ > PBS *‍‑anti̯‑ > PS *‍‑anti̯‑ (CS *‍‑ǫtʲ‑) > OCS ‑ǫšt‑; PIE pst.act.ptcp *‍‑us‑i̯‑ > PBS *‍‑uši̯‑ > PS *‍‑uxi̯‑ (CS *‍‑ŭš‑) > OCS ‑ŭš‑. This innovation is shared with Baltic, cf. the active participles formed from OCS nesti ‘carry’ and Lith. nèšti ‘carry’:

Infinitive: The Common Slavic infinitive marker *‍-ti may reflect PS *‍-tī or *‍-tē̆i. Since the Slavic infinitive marker is underlyingly accented, it is most likely that it corresponds to the locative singular (not the dative singular) of an i-stem, i.e. PS *‍-tēi̯ < PBS *‍-tēi̯ < PIE *‍-t-ēi̯ – because the i-stem locative singular is also accented in Slavic, e.g. PS loc.sg *‍nakˈtēi̯ (CS *‍notʲì), as opposed to dat.sg *‍ˌnaktei̯ (CS *‍nȍtʲi) with non-final accentuation.

Supine: The Common Slavic supine marker *‍-tŭ < PS *‍-tu < PBS *‍-tum, is originally the accusative singular of a tu-stem (Ved. inf -tum and Lat. sup -tu). East Baltic also uses this form as a supine, e.g. Lith. vèstų and Latv. dial. ȩ̂stu, while in West Baltic (Old Prussian) the form is used as an infinitive, e.g. boūton ‘be’.
