selda

child

selda adj.?noun? (meaning not clear, related to seldë "child" (meaning changed by Tolkien from "daughter") and seldo "boy". Thus selda may be an adjective "childlike", since -a is a frequent adjectival ending. Alternatively, as suggested in VT46:13, selda may be a neuter noun "child", corresponding to masc. seldo "boy" and fem. seldë "girl" (before Tolkien changed the meaning of the latter to "child"). (SEL-D, cf. VT46:22-23)
