"If you come home, you will take bath"
Translation:Mkija nyumbani mtaoga
Definitely! We have no clue telling us if it's plural or singular in the English sentence. Singular is always my first assumption so all these times when there's m- instead of u- are frustrating, and a lot of the time you can't report them because Duolingo says you've made a typo. (I wish we could change a setting to say typos are unacceptable.)
Good thing I was just now able to report the singular form. I hope they deal with it quickly.
