köken: From Middle Persian lʾs (/rāh/, “road, way”) from Proto-Iranian *Hrāθáh, from Proto-Indo-Iranian *Hrātʰás, from Proto-Indo-European *Hret-. Compare Old Armenian ռահ (ṙah), borrowed from Middle Iranian.
köken: From Middle Dutch buse, of uncertain origin, plausibly representing an umlauted byform *beusju of Proto-West Germanic *beusu (“rush, bentgrass”) which gives Dutch bies. For the "television" sense, compare English tube.
hole, gap, opening · aperture · hole (lack of an electron)
çekim: çoğul aukot · tamlayan aukon
köken: From Proto-Finnic *aukko (compare Estonian auk, Votic aukko), either derived from the same root as avata, aukea, or alternatively proposed to be a borrowing from Proto-Germanic *augô (“eye”).
pipe, tube, especially a water pipe · hollow reed or cane · shepherd's pipe, pipes of Pan
çekim: çoğul fistulae · tamlayan fistulae
köken: Unknown. De Vaan thinks the most promising connection is with festūca (“stalk, straw”) and fistūca (“pile driver, ram”), built on a stem *festo- which may be connected to ferula (“fennel; staff”) by a root *fes- (“hollow stalk”). This makes any relationship to findō (“cleave, divide, split”) unlikely.
