Dan. alm n. “elm-tree”
A noun for “elm-tree” derived from the root ᴹ√(L)ALAM (Ety/ÁLAM). It does not seem to be a direct cognate with either ᴹQ. alalme or N. lalf. Helge Fauskanger suggested it might be derived from a primitive form *✶almā (AL-Nandorin/alm), but I think it may instead be derived from *✶alamā.
My rationale is that this word did not go through the vowel-breaking before a cluster starting with liquid [l] or [r] seen in other words like ealc. This can be explained if, at the time of vowel-breaking, this word had the form alamā̆, and thus had no applicable cluster of consonants. The middle [a] would then be lost later through the Danian syncope.
