Etymology
Etymology Information

'porous' originates from Latin, specifically the word 'porosus', where 'poros-' (from Greek 'poros') meant 'passage' or 'pore'.

Historical Evolution

'porous' changed from Latin 'porosus' (itself from Greek 'poros') into Late Latin and then entered English via Middle English as 'porous', eventually giving the modern adjective 'porous' and the adverb 'porously'.

Meaning Changes

Initially, it meant 'full of passages or pores', and over time it retained this basic meaning while extending metaphorically to describe things that are permeable or not strictly sealed/controlled.
