Etymology

Origin of blotch

1595–1605; perhaps blend of blot 1 + botch 2

Explanation

A blotch is an uneven spot or blemish, like the itchy blotches you get all over your arms after tangling with the poison ivy in your back yard. Etymologists guess that blotch comes from blot, "spot or stain," influenced by patch — so you can think of a blotch as a patchy stain. The word is frequently used to describe skin that's discolored, like the blotches you get on your cheeks after crying, or the painful blotch on your back where you forgot to apply sunblock. Use it as a verb, too: "The ketchup squirted from his hamburger and blotched his new white shirt."
