permeability

the word permeability is a modern scientific term built upon classical foundations. its core, "permea", originates from the latin 'permeare', a compound of 'per-' (through) and 'meare' (to go, to pass), which itself may trace back to the proto-indo-european root mei-, meaning "to change, go, move". the suffix "-bility", denoting a capacity or quality, descends from the latin '-bilitas'. thus, the literal construction "capacity to pass through" perfectly captures the modern abstract meaning, describing the inherent quality of a material that permits the transmission of fluids, energy, or fields.

Structure: permea (pass through) + bility (capacity or quality) "permea" is derived from the latin verb 'permeare', meaning 'to pass through', from 'per-' (through) + 'meare' (to go, pass). "bility" is a suffix forming nouns indicating a quality or state, from latin '-bilitas', via old french '-bilité'.
