Swahili yes and no
I finished the Swahili tree a couple of months ago and since then I've been practicing (on the duolingo app) everyday.
I recently realized that I never learned how to say "yes" or "no" in Swahili! It seems like those words should be in there.
yes = ndiyo (naam)
no = hapana (la)
the form for yes is spoken I guess just "dio" (correct me otherwise), while "hapana" for "no" is spoken like "habana", and "la" is the shorter arabic from, which is also used.
