Telefol is a
subject–object–verb language.
Verbal aspect Telefol has a rich aspectual system. Telefol verbs have "punctiliar" (momentary/completed) and "continuative" stems.
Counting system Telefol uses a base-27 counting system. This is mapped onto the body by counting each of the following: the left pinky to the left thumb (1–5); the wrist, lower arm, elbow, upper arm, and shoulder (6–10); the side of the neck, ear, and left eye (11–13); the nose (14); and similarly on the right side in reverse order, from the right eye to the right pinky (15–27).
Kinship Telefol has
dyadic kinship terms (terms referring to the relationship two or more people have to each other), which are uncommon in the world's languages and not prevalent in Papua New Guinea. However, they are a salient feature of the Ok languages. Related terms are found in
Oksapmin,
Mian, and
Tifal. ==Evolution==
