widower comes from Middle English widewer, a masculine formation from widewe ('widow') with the agentive/masculine suffix -er, from Old English widuwe ('widow'), from Proto-Indo-European *h₁widʰéwh₂ ('widow'). The path is chiefly one of transmission: an older form is taken into English, with the word's shape and meaning carried through the language names and forms preserved in the history. In modern use, the noun sense is "a man whose spouse has died and who has not remarried", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as widow, widowhood, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Old English widuwe, Proto-Indo-European *h₁widʰéwh₂, which anchor the explanation in named linguistic material.
