damp (verb): (excerpted from OED) to dull, deaden; to impose or to act as a resisting influence on (an oscillation or vibration of any kind) so that it is either progressively reduced in amplitude or, if the resistance is sufficiently great, converted into non-oscillatory return to an equilibrium position.
dampen (verb): to make slightly wet. The OED says the use of this word as a synonym for “damp” (verb) is “now chiefly U.S.”
Another confusion I have encountered is between ‘oryx’ and ‘aurochs’, a kind of primitive cow that is now extinct. The two words look very different, but sound almost the same in some accents.

Not to mention petal.
Also medal (a decoration, as in Medal of Honor)/metal (a substance like iron or copper)/mettle (good character)/meddle (to interfere).
How about “pus,” a discharge from an infection, vs. “puss,” a nickname for a cat (or sometimes female genitals).
Very nice! (Though, I have to say e.g. I pronounce “metal” with a “t” and “medal” with a “d”.)
