Etymology
Origin of blot1
First recorded in 1350–1400; Middle English noun blot(te); orign uncertain; perhaps akin to Old Norse blettr “blot, spot, stain”; the verb is derivative of the noun
Origin of blot2
First recorded in 1590–1600; origin uncertain; perhaps from Low German blat, akin to bloot “bare, exposed, unprotected”; possibly cognate with Dutch bloot, German bloss bare
Explanation
A blot is a dirty smudge, mark, or stain, like the giant blot of ketchup that remains on your shirt long after the hotdog-eating contest is over. A blot tends to mar or dirty a pristine surface, whether it's an ink blot on the book report you spent hours writing, or a blot of black paint on a white kitchen counter. Figuratively, a blot is something that dirties a person's reputation: "The scandal was a blot on the presidential campaign." As a verb, blot can mean "obscure," like when you use your hand to blot out the sun, or "dry a wet spot," the way you blot spilled tea with your napkin.
