tense	suffix	gloss	example
remote past	-yai	REM	nam inayeha We ate a long while ago.
recent past	-yao	REC	nam inayehi We just ate.
past	-ye	PST	nam inaye We ate.
present	not marked		nam ina We eat. / We are eating. / We do eat.
future	-tli	FUT	nam inatli We will eat.
immediate future	-tlao	IMM	nam inatlihi We will eat soon/now.
distant future	-tlai	DIS	nam inatliha We will eat a long while from now.

The remote and recent pasts, as well as the immediate and distant futures are negated by the preceding negative nke rather than the negative suffix -k.
Kala does not distinguish perfect and imperfect aspects of the verb (e.g. "I ate", "I used to eat", "I have eaten", "I had eaten").
If a temporal adverb is used, the tense suffix may be omitted.

Example: We ate yesterday.
