Key unmarked stative verbs express present-tense function, as in
Sab can also appear with the present-tense marker, as in
Yo tə sab.
In the past, sab is conjugated as expected, i.e. sabew 'found out, came to know'. Note that the semantic interpretation of sabew expresses the beginning of knowing. That is, it has an inchoative interpretation.
Unmarked, kere 'want, need' has present-tense interpretation.
Pari ag kere.
[me water want]
'I want/need water.'
The past-tense form of kere (i.e. keri) is not heard much. The form kere is used in past contexts as well.
Other stative verbs, such as siti 'feel' behave like dynamic verbs in terms of their marking. Thus, examples (d-e) are completely acceptable.
Pari friw siti-n.
[me cold feel-PROG]
'I'm feeling cold.'
Dʒaner su mes,
[January GEN month]
yo tham friw tə siti.
[I always cold PRS feel]
'I always feel cold in January.'
