Qenya 

aran

noun. child

This word first appeared as ᴱQ. ar (arn-) “child” in the Qenya Lexicon of the 1910s (QL/32) and its stem form arn- appeared in the Poetic and Mythological Words of Eldarissa (PME/32). The word reappeared in Early Qenya Word-lists of the 1920s (PE16/135), but in the Early Noldorin Dictionary the Qenya form was given as arne. In the Declension of Nouns from the early 1930s, the word appeared as ᴹQ. aran (arn-) “child” (PE21/19), but there is no sign of it from this point forward, probably displaced by Q. aran “king”.

pronoun. that

ména

noun. region

seldo

noun. child, child [m.], *boy

A word for a (male) child in The Etymologies of the 1930s added to its entry when the meaning of the root ᴹ√SEL-D was changed from “daughter” to “child” (Ety/SEL-D). It was written above its feminine equivalent ᴹQ. selde and an apparently neuter form ᴹQ. selda was written to the right, making seldo likely the masculine form as suggested by Carl Hostetter and Patrick Wynne (EtyAC/SEL-D), hence = “✱boy”.
