Is yous a proper word

Answer 1

No, "yous" is not considered a proper word in standard English grammar. It is a nonstandard or colloquial variant of the plural second-person pronoun "you." In formal writing and speech, it is typically recommended to use "you all," "you guys," "you both," or simply "you" to address a group of people.

Answer 2

Although not commonly used anymore, (except for poetry) t'was is a perfectly good word, a contraction of "it was." T'was the night before Christmas...T'was brillig and the slithy toves did gyre...but probably not T'was really hard homework last night.

Answer 3

Yous, the plural of you, is a Middle-English word which is no longer used, or very rarely used, in modern English. It was a variation of the Old-English word "ye".

It is still used in some northern-English dialects, such as in Liverpool, Ireland and parts of Scotland (ie "I wish yous stop annoying me!"). But it is very rarely written and basically just exists as a dialect/accent.

It's similar to the American-dialect word "y'all". While it is used in American accents and dialects, it is not a proper written word.

So for literature, your answer is no.

But for northern-English accents, yes (although it is still not a written word).
