Let's list often confused terms

One of my favorites is peak and pique.

You have piqued my interest, but my interest has not yet peaked.

That reminded me of esoteric vs. erotic.

moot vs. mute

spayed vs spaded

We had our cat spayed, but when the operation went bad, we spaded a hole in the garden in which to bury her.

FYI, the official term is now voxel, which stands for “Volumetric picture element.”

How very beggardly of them.

spendthrift?

i’m not sure how often some of these terms are confused in real life. rogue and rouge? esoteric and erotic?
