I have never heard the word "paa" used for gazelle, only "swara" or swala." My dictionary does not list the word "paa."
It is used. I remember it from way back. It means fly, roof and gazelle.
My dictionary contains " paa" - gazelle, roof, and...".blue duiker"- what I don't know what is this.
Swara is - gazelle and - swala - as the first meaning is - antelope
The letters "L" and "R" are often interchanged in Swahili, because they have similar pronunciations. So Swara is sometimes spelled Swala, though they mean the same thing, gazelle.
a duiker is a species of southern african antelope. many of the swahili animal terms are not meant to be super precise, but it's the right ballpark.
Paa comes from Proto-Bantu *m̀pàdá, which both means and is the source of English impala (via Zulu).
Why not antelope?
