Past and present are not obligatorily marked in the language. Examples with unmarked stative verbs tend to have a present tense interpretation. Unmarked stative verbs with a past tense interpretation were not attested. Half of the examples with unmarked dynamic verbs tend to have a present tense interpretation, the other half has a past interpretation.
