“I love being apart of your life.”
Thanks. I love being A PART of yours, too. Apart means separated. “She ripped our friendship apart when she spelled ‘a part’ incorrectly,” for example. (That is not true. While I love good spelling and grammar, I’d never end a friendship over it.)
A part means part of something. “Striving for good grammar is a part of me.”
Here’s a tip for knowing which one to use, which I got from englishgrammar.org. If you’re struggling with whether it’s apart or a part, take away the “a.” Does the sentence still make sense? If it does, you keep that space between “a” and “part.”
“Good grammar is part of me.” Sure, that makes sense. Must be a part.
“I miss you when we’re part.” Hm. Nope. Must be apart.
Now that we’ll never be apart on this issue, let’s move on to something a lot of people do.
