This is something that I think about a lot, and I just wanted to know: why do people put 's for plural nouns? For example, I was reading something the other day that said this:

-> If you have any further Q's (meaning questions) please ask/answer the Q's

-> she bought some carrot's for dinner

What confused me were the discrepancies throughout because in another paragraph it would be phrased like this (without the apostrophe):

-> keep the Qs in mind

EDIT: I have now understood it is for clarity, so thank you! Would it be correct to use 's plurals in formal essays, articles, etc, or would it be correct to use - for example - PhDs?

In a similar vein, when quoting evidence, is it better to use " " or ' ' as quotation marks (for example in essays and news articles, etc)? I've always used ' ' as I only use " " for speech marks, but if anyone has a reason, let me know!

\By the way, in case someone has asked this before, I'm very sorry; I didn't know**
Thanks in advance!

Hello! I’m currently writing a toast for my sister’s wedding. As part of my introduction, I’ve drafted “I had the great honor of growing up as bride’s little sister, a title that has never failed to precede me.” It feels a bit unnatural to me, but I’m wondering if that’s because I’ve been looking at this for too long 😂

I keep seeing people in comment sections using verbs without auxiliary verbs.

For example:

The bathroom needs renovated,

The sink needs cleaned.

Where is this coming from and why am I seeing it everywhere now?

Over time i will find myself finished school life

i know i can say "I will find myself finishing something...

But can i also use past tense with the same structure

Thanks for your answers
