Etymology
'impermeable' originates from Latin, specifically the word 'impermeabilis', where the prefix 'in-' meant 'not' and 'permeabilis' came from a root meaning 'able to be passed through' (from 'permeare').
'impermeable' changed from the Late Latin word 'impermeabilis' and via Romance (e.g., French 'imperméable') entered English as 'impermeable' and later produced the adverb 'impermeably'.
Initially, it meant 'not able to be passed through'; over time it has retained this core meaning in modern usage.
