The Quenya word for “father”, derived from the root √AT(AR) (PM/324; WJ/402; VT48/19).
Conceptual Development: ᴱQ. atar “father” dates all the way back to the Qenya Lexicon of the 1910s, though in that document it was “a more solemn word ... usually to 1st Person of the Blessed Trinity”, as opposed to more ordinary ᴱQ. attu “father” (QL/33). In the English-Qenya Dictionary of the 1920s, ᴱQ. atar was the ordinary word for “father”, but with variant archaic form †attar (PE15/72). ᴹQ. atar “father” reappeared in The Etymologies of the 1930s as a derivative of the root ᴹ√ATA of the same meaning (Ety/ATA). It appeared again in the Quenya Verbal System (QVS) from 1948 in various inflected forms (PE22/118-119). It continued to appear regularly in Tolkien’s later writings. Thus this word was established early and retained its form throughout Tolkien’s life with only minor variations.
A neologism for “catch, capture” coined by Fiona Jallings, inspired by N. gad- “catch” based on the root ᴹ√GAT.
