Sense: adjective/1
Fleeting is the everyday word — it describes anything that passes quickly, from a smile to a moment of happiness. Transitory is slightly more formal and often applies to stages or conditions that change by nature, such as adolescence or a political phase. Ephemeral carries a literary flavour and is strongly associated with the natural world (ephemeral flowers, mayflies, spring blossoms). Evanescent is the rarest and most formal of the four; it suggests something fading gradually or dissolving before your eyes, like a memory or a vapour. In most daily situations, fleeting is the best choice. For formal writing about nature or time, ephemeral or transitory fit better.

Etymology
Fugacious comes from Latin fugax (meaning 'fleeing, swift, shy') combined with the English suffix -acious ('tending to'). The root fugere means 'to flee', and the sense of 'quick to disappear' grew from the image of something running away or slipping out of sight.
