I was never aware "JACK and JILL' should take the pronoun Ils. It was my belief ILS was reserved for all boys only.
So now I see vous addressing the individuals IN the group. Sort of like ILS is they and VOUS is similar to America's deep South as y'all, or the northeast as in you guys.
So within the poem/song Jack and Jill went up the hill one wouldn't use the pronoun VOUS as it would change the meaning. Is that correct?
Not Y'ALL or You guys or VOUS went up the hill... Jack and Jill are not the audience.
THEY or ILS went up the hill to fetch... The audience is being addressed. Not Jack and Jill.
Dear professor, is that about right?
