From Proto-Indo-European *dʰ(e)h₁s-. Cognate with Phyrigian δεως (deōs, “to the gods”) and probably Old Armenian դիք (dikʿ, “pagan gods”) and Latin fēriae (“festival days”), fānum (“temple”) and fēstus (“festive”).
Alternative suggestions connect it to *dʰewh₂- (“to rise in smoke”), whence also Ancient Greek θυμός (thumos).
Despite the superficial similarity, the word is not related to Latin deus.
