Why YSK?
The first person who typed “should of” probably heard of it in real life that was meant to be “should’ve”, they typed “should of” online and readers thought that it’s grammatically correct to say “should of” which is in fact wrong and it became widespread throughout the years on Reddit.
I hope something could start to change.
I’m guilty of should of, but I usually use shoulda as I tend to type how I talk, and my pronunciation is somewhat lazy.
However I’m of the opinion that as long as the point is gotten across, there is no wrong way to communicate. Alot of people actually say “should of” while speaking, and it only makes sense that they’d type that way, usually without a second thought till someone interrupts a discussion with grammar correction, which let’s face it, brings NOTHING to the table.
