pore: English has two words pore. The older, ‘look attentively’ [13], may go back to a hypothetical Old English *pūrian, which might make it a relative of the nearly synonymous peer [16]. The pore in the skin [14] comes via Old French pore and Latin porus from Greek póros ‘passage’, a descendant of the Indo-European base *por- ‘going, passage’, which also produced English fare, ferry, opportunity, and port. The development of the word’s anatomical sense began in Greek. Porous [14] is derived from it.
=> peer; fare, ferry, opportunity, porous, port
