I saw it again today: “phase” for “faze.” Let’s look at these words, folks. I know I can straighten you out.
If you want to tell me that something didn’t upset you, didn’t bother you, you’ll say “That didn’t faze me in the least.” FAZE. The word, an Americanism, dates to 1830 and can be traced to Kentish dialect, Old English, and Proto-Germanic. You can look it up for yourself at the Online Etymology Dictionary. Likewise, you can be “unfazed.” Whatever it was didn’t bother you. You’re unfazed. “Yeah, that truck nearly sideswiped me when I skidded on black ice, but I was in control. Didn’t faze me at all.” (You’re a bald-faced liar, but you’re using the correct word. I’ll let it slide. Heh.)
If you’re Kitty Pryde, you can be unphased—but the preferable term is “out of phase,” honestly. Ask Marvel Comics. They’ll set you right. PHASE. This word can be traced to both Latin and Greek. Again, don’t take my word for it. Look here for yourself. There’s phase as in “she’s going through a phase” and phase as in “we’ll phase this in over time.” Phase. A much newer meaning from science fiction and comics has to do with being out of sync, literally; that’s what happens with Kitty. She phases by dropping out of (or is it into?) sync with time and space. Are you a mutant like her? I didn’t think so. (You might be weird in your own wonderful way. I can’t say, as I don’t know you.)
I’m delighted to see that this error is only given a Stage 2 rating on Garner’s Language Change Index. It’s not too late to stop the trend. Just because “everyone says it” doesn’t make it right. And so far, we’re still a long way off from “everyone.” Frankly, the confusion fazes me every time.
