y'all is poor english for a language course
Considering the rest of the course, this is a weird hill to die on.
I disagree - it is best for distinguishing between singular and plural for some.
It's not poor English. Just non-standard. But it probably shouldn't be the main translation.
I am referring specifically to the use of abbreviations, not the use of ‘you all’.
"All of you come, except Rehema" is another possibility.
