Re: Meaning and analysis of *Dye:us

I used to have the impression that the PIE root [dye_u-] or [diye_u-] meant "the bright daytime sky", whence Sanskrit "day" and "sky", and Latin "die_s" = "day".

Latin "ventum" = "wind", Greek "awe_r" (air), "awe_ti" (it (= a wind) blows) (w = digamma); the PIE root for "air" seems to be H2-W-H1, and Vayu may be this root plus a suffix -yu-.

(Root H2-W-H1 also means "air" in Arabic; Arabic seems to have kept its laryngeals to the present day!)
