Formation of the negative Imperative:
Sg: u + si + root (if last letter = ‘a’ it changes to ‘e’
Pl: m + si + root (if last letter = ‘a’ it changes to ‘e’
Example: kukimbia - to run
Sg: u + si + kimbi - a becomes e + usikimbie - Don’t run!
Pl: m + si + kimbi - a becomes e + msikimbie – Don’t run (you all)!
Verb stems ending in other letters than a don't change Ex. kufikiri (to think) - usifikiri (Don't think)
After reading a lot of comments on this issue in this course, I now agree with those who say that "you all" is only used in certain US dialects, and -m- should be translated as "you" because that is what the rest of us would actually say in standard English.
As a general principle, it would be wrong to translate literally where English doesn't make such a distinction, just to let them know that we recognize the grammatical category. In the same way, we shouldn't write "you (accusative)" just because English doesn't distinguish between you as subject vs. object (in the way it does with the pronouns I vs me and she vs her).
It seems so (among many other inconsistencies in this course).
For those who actually have "you all" in their dialect, it shouldn't be marked wrong, but then it just depends which correct alternatives (e.g. "all of you", "both of you") are reported by how many students and in how many lessons. If we are lucky, the course developers detect a pattern in the reports and revise the accepted answers for a whole lesson. (At least, I am guessing that's how it works.) Then we would get more consistency.
