I try not to be Mr. Grammar Nazi (Can you even say that anymore?), but it really gets under my skin when people use “apart” when they mean to say “a part” because they are literally saying the exact opposite of what they mean.
If somebody is “a part” of something, it means they are included with that thing; they and that thing are a package deal.
If somebody is “apart” FROM something, it means they are not near or not included with that thing; the two are NOT a package deal/together.
Example of a post I saw recently: “I love you so much. You are apart of my soul.”
Basically saying they are NOT a part of their soul, but on the contrary, are apart from their soul as in there is distance between their significant other and their soul. Sorry, I know this probably isn’t a new thing. I’ve just been seeing it so much recently and it ticks me off.
