I remember hearing dhakam from some language challenges so i can't point to a source right now. If you're interested in looking for similarities between languages i have a good video for you, at least when it comes to somali and oromo.
I’ll try to find the meaning or which dialect uses that word.
the clip you just shared is a horrible example, she has a bad accent and her dialect is western Arsi a mix of Arsi and Shawa. She can’t pronounce the dh in afaan Oromo. An example of this is in one of her vid, the word for rock she pronounced eega but the word is spelt and pronounced dhaga. A lot of central Oromos have a hard time pronouncing some words.
