Verbs do not change for tense. The particle me indicates the general past tense and the particle ke indicates the general future tense. There is no perfect tense.

Wo gia - I go
Wo me gia - I went
Wo ke gia - I will go

If a verb happened in a specific time period, the particles are not required, as the tense can be inferred from the context.

Wo ant-hiu gia - I went yesterday
Wo post-hiu gia - I will go tomorrow
