[ˈfɔ.kʊs], [ˈfɔː.kus]
Origin* The origin is uncertain. Usually connected with Old Armenian բոց (bocʻ).
* Some connect this along with faciēs, facētus, fax to Proto-Indo-European *bʰeh₂- (“to shine”). In that case, cognate at the root level with Sanskrit भाति (bhā́ti), Ancient Greek φαίνω (phaínō, “to shine”), etc.
* Matasović, and Hamp before him, opt to derive this from Proto-Indo-European *dʰegʷʰ- (“to burn”); Matasović believes that the -c- would have spread from the nominative of a root noun *dʰṓgʷʰ-s (> *dʰṓkʷʰ-s).
