If your interest has been aroused by something, then it has been piqued, which means “to stimulate.”
Not “peeked,” which means to sneak a quick look at, nor even “peaked” which means pointed, or, if you make it two syllables, peak-ed, is a colloquial term for looking a little sickly.
PIQUED. Learn it, love it. USE it.
Thank you. Carry on.
