"A few large people"
I had to look up "wanene," which wasn't in the dictionary, but "-nene" is, adjective meaning "fat."
"A few large people" as "A few fatties"?
It should go at the end of the noun phrase. I wrote watu wakubwa wachache and it was accepted.
I think, tho I am not 100% sure that quantifiers like 'few' or 'many', etc. always come at the end, after all the other adjectives.
