“Copacetic” is an informal slang word used to convey that everything is alright. It’s become associated with 1960s American hippie and surf culture, but that’s likely not the true origin of the term. Some historians trace “copacetic” to 19th-century African American dialects, while some lexicographers point to origins in the Pacific Northwest. Others believe it was adapted from a Yiddish phrase. Whatever the beginnings, picture the classic surfer hand gesture of the thumb and pinky sticking out for a visual representation of the easygoing adjective “copacetic.”
