The spelling of the word "aruk" can actually be a bit tricky. In IPA phonetic transcription, it would be written as /ɑrʊk/. The first sound, the "a" sound, is pronounced with an open mouth and the back of the tongue raised. The "r" sound is made by vibrating the tongue against the roof of the mouth. The "u" sound is pronounced as a short "oo" sound, and the "k" sound is made by releasing a burst of air from the back of the throat.
