Morphology
fluorite = fluoride (opaque) = fluor + ite
The combining form 'fluor-' is not a standalone English word for most learners and '-ite' is a technical mineral suffix, so the meaning is not directly derivable by average learners.
Etymology
The word fluorite comes from the Latin root fluor-, from fluere 'to flow', because people used it to help metal flow when it was melted. You can see the same root in fluid ('flow') and fluorescent ('glow'), so the name links its old use in metal work and the way some crystals 'glow' under ultraviolet light.
