Etymology

The adjective "flighty" is a native English formation, built upon the noun "flight." While "flight" commonly refers to the act of flying, its older and more fundamental sense relates to the act of fleeing or escaping. The suffix "-y" adds the meaning "characterized by." Therefore, the literal construction is "characterized by flight." This originally described creatures, like skittish horses, prone to sudden, uncontrolled movement. Over time, the metaphor shifted from physical capriciousness to mental and behavioral instability. A "flighty" person is thus one whose mind or attentions seem to flee erratically from one subject to another, leading to the modern sense of frivolous irresponsibility.
