LatinEdit
EtymologyEdit
Of uncertain origin. Some connect it with rādīx and rāmus. Tucker suggests Proto-Indo-European *neredʰ- (“extend forth, rise, outward”) akin to Sanskrit वर्धते (vardhate, “rise, grow”), or from Ancient Greek ἄρδις (árdis, “sharp point”).[1] May ultimately be from Proto-Indo-European *reh₁t- (“bar, beam, stem”).

- a staff, rod
- a ray of light (also reflected)
- (according to an ancient theory of vision) a ray extending from the eye to the object seen
