Snafu (noun) (adj) (verb)
A confused or chaotic state; a mess. Chiefly North American.
1940s: acronym from situation normal: all fouled (or fucked) up.
“The current administration is just one big snafu!”
A person who inspires or influences others, especially one prominent in a particular sphere.
Late Middle English: from Old French luminarie or late Latin luminarium, from Latin lumen, lumin- ‘light’. Modern meaning comes from the more archaic meaning ‘a natural body that gives light, such as the sun or the moon.’
(archaic) a momentary sick of faint feeling. Modern usage is an uneasy feeling of doubt about one’s actions, usually used in the negative ‘no qualms’.
Early 16th century (in the sense ‘momentary sick feeling’): perhaps related to Old English cw(e)alm ‘pain’, of Germanic origin.
