An adjective for “snouted” in The Etymologies of the 1930s appearing only in a reduced form as the final element of N. annabon “elephant” = “long-snouted” (Ety/MBUD). It was derived from primitive ᴹ✶mbundā under the root ᴹ√MBUD “project” (Ety/MBUD), where the u became o via a-affection.
Neo-Sindarin: In keeping with the principle that nd remained “at the end of fully accented monosyllables” in Sindarin (LotR/1115), I would adapt this word as ᴺS. bond “snouted” for purposes of Neo-Sindarin.
