The present participle of an archaic or obsolete verb, possibly referring to speaking Greek, adopting Greek customs, or treating as Greek.
From 'grek' or 'Greek' as a verb form, with '-ing' forming the gerund; likely emerged in contexts of medieval religious or academic discourse where Greek learning was particularly notable.
Medieval scholars used 'greking' to describe the moment learning Greek became possible—it was such a rare skill that the act of learning the language itself became a noteworthy verb in academic circles.
