andon

noun. great gate, great gate, [ᴱQ.] door, gate

A noun for a “great gate” in The Etymologies of the 1930s, an augmentative form of ᴹQ. ando “gate” under the root ᴹ√AD “entrance, gate” (Ety/AD).

Conceptual Development: The word ᴱQ. andon first appeared in the Early Noldorin Dictionary of the 1920s as a cognate of ᴱN. ann “door” (PE13/137, 160). It was also an element in the name ᴱQ. Andonavestan “Gates of Summer” (PE13/143, 160). This earlier iteration was not augmentative as it was in the 1930s.
