"Jamila washes clothes."
Translation:Jamila anafua nguo.
kusafisha = to clean
kuosha = to wash [general]
kufua = to wash [clothes]; to beat
kunawa = to wash [hands, face] ...
osha is usually used to describe cleaning plates. fua is mainly used for clothes.
Because you don't use the verb "safisha" for clothes. Just like in English you don't wash a table, but clean or wipe it.
