dêlos

According to Beekes and LIV, from Proto-Indo-European *deyh₂- (“to light up, shine”), and related to δέατο (déato, “seemed”). Compare Sanskrit दीप् (dīp, “to blaze, glow”), and see there for more cognates.

Another theory derives the word from Proto-Indo-European *dyew- (“heaven, sky; to shine”). (Can this⁽⁺⁾ etymology be sourced?)
