Synonyms & Antonyms

Root Explanation

Fluorescently → It is formed from "fluorescent" (from Latin "fluere", meaning to flow, combined with the suffix "-escent", meaning becoming) and the adverbial suffix "-ly" (meaning in a manner of). The word "fluorescently" describes the manner in which something exhibits fluorescence, or the property of emitting light while absorbing radiation.

Memory Tip

Think of something 'becoming' ('-escent') that 'flows' ('fluere') with light — that's how fluorescently describes the way something shines.
