PEAK/PEEK/PIQUE Mixing these up is direly easy. A peak is a summit; a peek is a glance. The ea in “sneak” inspires many an erroneous “sneak peak.” No, please: It’s “sneak peek.” (Unless you find yourself jetting through a cloud and suddenly about to collide with a mountain, in which case, sure, that’s a sneak peak.) A fit of pique is a peeved little tantrum; to pique one’s interest is to stimulate and excite it.
