"A few large ones"
Again, in strengthening the People section of the learning tree I'm getting material that was not in the 6 lessons. Mkubwa was taught as large and no mention was made of Wanene.
Wanene are fat or stocky people. Just calling them large is a bit euphemistic.
From the English it is impossible to tell "ones" what? Animals, fruits, people... Thus, it is unclear whether to use Wanene. Also, not that common of a word, depending on region.
Probably because "Wakubwa" would be accepted as a translation of "big ones". As it's just 1 letter different from what you put, it's accepted as a typo.
