vanimalda

your beautiful

vanimalda adj. with suffix *"your beautiful"; Arwen vanimalda "Arwen your beauty = beautiful Arwen" (WJ:369, cf. PE17:55).The ending for sg. "your" normally appears as -lya rather than -lda (which according to late sources is rather the ending for plural "your", here inappropriate). Originally Tolkien seems to have intended vanimalda as an inflected form of vanima "beautiful", the ending -lda expressing comparative, superlative or simply "exceedingly" (PE17:56: vanimalda = "exceeding fair"). However, since this ending was later revised out of existence, Tolkien reinterpreted the word. The Second Edition of LotR changes one letter to arrive at the reading vanimelda, q.v. for Tolkiens new explanation.%
