Over and over I see this error:
His comment peeked/peaked/piquet my interest.
I see it a lot on blogs. I’ve also seen it recently in a couple of published books.
The correct spelling of this word is piqued, meaning, in this case, that his comment created an interest or curiosity in the listener’s topic.
Pique can also be used to indicate irritation, resentment, frustration, but this usage is less common in America English.
