Conjugation Patterns: -eie 

In this section, we focus on how -eie verbs are conjugated across different tenses.

Present Tense:

    The verb retains its -eie ending for all pronouns, except for the third-person singular, which drops -e and adds -s.

    Examples:
        ta conveie → conveis
        to obeie → obeis
        ta preie → preis
        ta sleie → sleis
        ta pôveie → pôveis
        ta sôveie → sôveis


Past Tense:

    The past tense drops -e and adds -d to the end.

    Examples:
        conveid
        obeid
        preid
        sleid
        pôveid
        sôveid


Progressive Tense:

    The -eie ending changes to -eyiŋ in the progressive form.

    Examples:
        conveyiŋ
        obeyiŋ
        preyiŋ
        sleyiŋ
        pôveyiŋ (the main stress is still on the -ey)
