evaporation
UK: ɪˌvæpəˈreɪʃən | US: ɪˌvæpəˈreɪʃən
n. the process of a liquid turning into vapor, typically due to heat
n. the disappearance or diminution of something, often abstract (e.g., hopes, funds)
The word "evaporation" stems from the Latin evaporare ("to disperse as vapor"), combining e- (out) + vapor (steam, vapor). The suffix -ion was added in Middle English to form the noun. The concept reflects the physical transformation of liquids into gas, later metaphorically extended to describe the gradual disappearance of intangible things.
