lintyulussea

adjective. having many poplars

A word for “having many poplars” from The Etymologies of the 1930s, a combination of ᴹQ. lin- “many” and an adjectival form of ᴹQ. tyulusse “poplar-tree” (Ety/LI).

Conceptual Development: This word also appeared with the same meaning from the 1910s and 20s as ᴱQ. lintyulussea, lintutyulussea “having many poplars” (QL/53), lintu(tu)lussea (PME/53) and [nominative] lintyulussean (PE16/80). The possibly duplicated tu(tu) in the early form of this word seems to be an artifact of the prefix ᴱQ. li(n)-; compare to limpa(pa)lasse(a) “much roaring” based on ᴱQ. palasse “splashing” (QL/53).
