My earlier writing is filled with the incorrect usage of who and that.  Even now, I oftentimes forget to make the distinction.  Throw in a which and now we’ve got a little more to think about.  Of course, who refers to people; which and that indicate groups or things.

She is the woman who I’ve been talking to about my writing.
The company that she works for prepares marketing and social media for its clients.
My article about body image, which I wrote for In With Skin magazine, can be read online or in print.

To understand a bit more about the ins and outs of that and which, just remember that introduces essential clauses, while which presents nonessential clauses.  (Note: essential clauses do not have commas surrounding them, nonessential clauses do.)

Who, that or which word, if any, causes you grief?
