S. Annúnaid pn. “Westron”
The Sindarin name for the “Westron” language (PM/316). Its initial element is clearly annûn “west”, but the meaning of the suffix -aid is unclear. It might be some variation on the gerund-suffix -ed/-ad seen in nouns like genediad “reckoning”, though this suffix usually forms nouns from verbs, not adjectives.
