Morphology
hydrofluosilicic + acid
This is a technical chemical name where the modifying element 'hydrofluosilicic' is a low-frequency, specialized coinage (built from roots like hydro-, fluo-, silicic) not listed in the learner-facing dictionary, so a B1 learner would not be able to parse its specific meaning or uses. Although 'acid' is transparent, that alone does not let a learner infer the compound's corrosive/toxic properties or its use in water fluoridation, so the overall MWE is not derivable from its parts for a typical B1 learner.
Etymology
Hydrofluosilicic acid comes from the name parts hydro-, fluo-, and silicic: hydro- points to 'water', fluo- to 'fluorine', and silicic to 'silicon' (the element in sand). So the name literally says an acid of fluorine and silicon in water, which fits why this is a strong, corrosive acid used in water treatment and industrial chemistry.
