IPA: /ˌɛf.ləˈrɛs.əns/
KK: /ɛfˌlɔːrˈɛsəns/
A process where something develops or unfolds, often referring to the blooming of flowers or the formation of salt crystals on surfaces due to evaporation.
The efflorescence on the wall indicated a moisture problem in the building.
Efflorescence is formed from "ex-" (meaning out) and "florescere" (meaning to bloom or blossom). The word describes the process of blooming or flowering out, often used in the context of salts forming on surfaces as they crystallize and emerge.
Think of something 'blooming out' — 'ex-' means out, and 'florescere' means to bloom. This helps you remember that efflorescence refers to the process of something blooming or crystallizing out.
