early 13c., pouren, "gaze intently, look with close and steady attention or examination," a word of unknown origin, with no obvious corresponding word in Old French. Perhaps from an unrecorded Old English *purian, suggested by spyrian "to investigate, examine" (cognate with Old Norse spyrja) and spor "a trace, vestige." Especially, but not originally, "to read something with steady perseverance" (late 14c.), with on or over. Related: Pored; poring.
late 14c., "minute opening, small orifice, or perforation" in the earth, a tree, the body of a human, animal, or insect, a bone, etc.," from Old French pore (14c.) and directly from Latin porus "a pore," from Greek poros "a pore," literally "passage, way," from PIE *poro- "passage, journey," suffixed form of PIE root *per- (2) "to lead, pass over."
