Jabarkan {| dari Bahasa Na'vi dalam bahasa melayu

Kata kerja are conjugated for tense and aspect, but not for person. That is, they record distinctions like "I am, I was, I would", but not like "Saya adalah, kami adalah, dia adalah". Conjugation relies exclusively on imbuhan sisipan, sama seperti imbuhan akhiran tetapi dimasukkan ke dalam kata kerja. Contohnya, "buru", adalah taron, tetapi "diburu" adalah t‹ol›aron, dengan imbuhan sisipan ‹ol›.

Terdapat dua kedudukan untuk imbuhan sisipan: after the onset (optional consonant(s)) of the suku kata kedua terakhir, dan after the onset of the final syllable. Oleh kerana kebanyakan kata kerja Na’vi bersuku kata dua, imbuhan secara amnya diletak pada suku kata awal dan akhir. Untuk perkataan bersuku kata satu sperti lu "be", they both appear after the initial onset, keeping their relative order.

Kedudukan imbuhan sisipan pertama diambil untuk tense, aspek, perasaan atau kombinasinya; also appearing in this position are participle, reflexive, dan causative forms, the latter two of which may co-occur with a tense/aspect/mood infix by preceding it. Tenses are past, recent past, present (unmarked), future, and immediate future; aspects are perfective (completed or contained) and imperfective (ongoing or uncontained). The aspectual forms are not found in English but are somewhat like the distinction between 'having done' and 'was doing'.
