Where this word comes from
Inherited from Old French sifler (later orthographically influenced by souffler), from Vulgar Latin *sīfilāre, probably an Osco-Umbrian influenced variant of Latin sībilāre (compare Spanish chiflar, Friulian sivilâ). Compare also the variant northern Old French dialectal form sufler (whence Norman sûfflier and Walloon xhufler), from a Vulgar Latin variant *sufilāre (compare Italian zufolare), as well as the dialectal subler from a form *subilāre (compare Italian sobillare, Romansh tschüblar, Romanian șuiera); in areas transitional to Franco-Provençal dialects is found the form sibler (compare also Occitan siblar, siular, Catalan xiular).
