Bad

Remember the time when “BAD” became “GOOD?”

Here’s a bit of the history of the word:

“Middle English: perhaps from Old English bǣddel ‘hermaphrodite, womanish man’”

“The meaning ‘uncomfortable, sorry’ surfaces in 1839, American English colloquial.”

“To go bad ‘putrefy’ is from 1884.”

“Not bad ‘fairly good’ is by 1771.”

“’My bad’ as an acknowledgement of a mistake is by 1995.”

“Ironic use of bad as a word of approval is said to be at least since 1890s orally, originally in African-American vernacular: It’s use in print is evident by 1928 in a jazz context.”

By the late 60s, it is well entrenched oppositional slang, along with words the likes of “cool,” “dread,” and “wicked.”

“Bad” can also mean “much” or “a lot.” – “I want that so bad!”
