I just spontenously added the word "concomitant" to a paper I am writing (Korean apologies).
I'm just surprised I knew the word. I can't define it, but I knew it was the exact word I was looking for. It's odd that way. I've never been a dictionary user, ever, and I can't tell you what most things mean with any precision. But I know it's the word I want here. Native language use is all about feel.
