To say "good afternoon" in an Igorot language, you would need to specify which specific dialect you're interested in.
For example, here are some possibilities:
* Kankanaey: "Napintas nga malem" (pronounced nah-peen-tahs nga ma-lem)
* Benguet: "Napintas nga malem" (pronounced nah-peen-tahs nga ma-lem)
* Ifugao: "Nangalngal nga malem" (pronounced nang-al-ngal nga ma-lem)
* Ibaloi: "Napintas nga malem" (pronounced nah-peen-tahs nga ma-lem)
If you tell me which specific Igorot dialect you're interested in, I can give you a more precise translation.
