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.
köken: Fuller form in dialectal fluieră, of uncertain or disputed origin; possibly from Latin flātūrālis (adj.) ‘blowing’, from flātūra ‘act of blowing’. Other theories suggest a Vulgar Latin root *flibula, from fibula (compare sense of flute in Latin tibia), or a derivative of the related verb fluiera, or a substratum (substrate) word. Alternatively, it may be of originally imitative origin. Compare…

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.
Back-formation from sípol (“to whistle”), from sí (“to howl, cry”) + -p (either an instantaneous suffix or a variant of the sound -v from the siv- stem of the base verb) + -ol (frequentative verb-forming suffix).
