si. Only
Czech gerunds inflect. The rules for formation are:
for vowel stems add -v- (Pol, Sorb -w-, Bel -u
˘
-), for consonant stems add nothing;
then add -
ˇ
si (Pol -szy, Bel -
ˇ
sy):
(195) Bel zrabı

‘to do’, [PastGer] zrabı

Czech gerunds inflect. For vowel stems add -v- as described above. Then for both
consonant and vowel stems add:
(196) [Masc] -ø, [Fem/Neut] -
ˇ
si, [Pl] -
ˇ
se:
r
ˇ
ı
´
c-i ‘to say’, [PastGer] rek-ø, rek-

si, rek-

se
koupi-t ‘to buy’, [PastGer] koupi-v-

si/-

se
Note that some past (perfective) gerunds may have the formation of the present
gerund:
(197) Rus vojtı
´
[Prfv] ‘to enter’, [3Pl] vojd-u
´
t, [PastGer] vojd-ja
´
Supine The supine survives only in Czech and Slovenian, and has effectively now
disappeared in Czech. It is used after verbs of motion in place of the infinitive,
though the infinitive itself is preferred (7.2.2.1).
The supine is formed by deleting the -i from the infinitive:
Cz: infinitive spa
´
t ‘to sleep’, supine spat (with its different quantity, the only
form still quoted as being distinct from the infinitive)
Sln: infinitive pe
&
ˇ
ci ‘to bake’ supine pe
`
ˇ
c
pı
´
ti ‘to drink’ supine pı
´
t
5.5.6 Athematic and auxiliary verbs
The athematic verbs ‘be’, ‘eat’, ‘give’, ‘know’ and ‘have’ of Proto-Slavic showed
-m in the 1 Singular present. This and the other endings were attached directly to
the present-tense stem, without a thematic vowel, hence the name ‘athematic’. The
generalization of the -m to many other verb classes has helped to make these verbs
more irregular than athematic in the modern context. We list below the main parts
of the verb ‘be’, which is also important as an auxiliary, as well as ‘eat’, ‘give’,
‘know’ and ‘have’ in Proto-Slavic (table 5.34), and those plus ‘want’ (regular in
Proto-Slavic) in sample languages (all still have some irregularity in the paradigms,
if only in the relationship between the infinitive and present-tense stems)
(table 5.35).
