A verb implied as an element of anglennatha “will approach” from the King’s Letter of the early 1950s. It is probably cognate to ᴹQ. lenna- “go” from The Etymologies of the 1930s (Ety/LED; EtyAC/LED). It thus likely had a similar meaning.
Neo-Sindarin: For purposes of Neo-Sindarin, I use glenna- mainly for “travel”.
