Etymology
the word fluorescent originates from the mineral fluorite, historically called 'fluor' in latin due to its use as a flux in metallurgy to make metals 'flow'. in the 19th century, the phenomenon of 'fluorescence' was named after fluorite because certain specimens of this mineral were observed to emit visible light when exposed to ultraviolet radiation. the suffix '-escent', meaning 'becoming' or 'beginning to be', was appended to create the adjective, literally describing something that 'begins to glow' like fluorite. thus, the term evolved from a literal reference to a specific mineral to describe the general physical property of emitting light upon excitation.
Analysis
fluor is derived from the latin 'fluor' (meaning 'a flowing', later applied to the mineral fluorite). escent is a suffix from latin '-escentem' (present participle ending of verbs meaning 'to become' or 'beginning to be').
