Northern Aslian
- ISO639-3:btq, Batek Deq, Batek Igaq, Batek Nong, Batek Tanum, Batek Teh and Batek Teq are ethnonyms of various Batek peoples. It remains unclear as to whether each is a different language or a variety. All currently fall under the ISO639-3 language code btq, with the exception of Batek Tanum (also known as Mintil) which has the language code ISO639-3:mzt. Insufficient research has been undertaken to ascertain whether this is warranted.
