Really random annyoing thing I've seen on boards a lot

If you're trying to say could/should/would have (insert rest of sentence here), please for the love of sanity and grammar don't say could/should/would of, this is not a thing, and has literally no meaning in the english language.

Alternatively (and correctly), say could've, should've, would've, or just leave it as two full words.

Thanks for reading my random grammar post about grammar, I hope this enlightened a few of my fellow boards users.
