stramen

Latin

Given the existence of parallel formations in Sanskrit स्तरी॑मन् (stárīman) and Ancient Greek στρῶμα (strôma), it may derive from Proto-Italic *strāmen, from Proto-Indo-European *stérh₃mn̥ (“that which is strewn; bedding”), from the root *sterh₃- (“to spread, scatter, strew”) +‎ *-mn̥ (deverbal abstract noun–forming suffix). However, the EIEC suggests that these formations may be independent, but parallel innovations.^[1]^[2] For the root, compare English strew, straw and Latin storea, strāges and torus.

strāmen n (genitive strāminis); third declension

Third-declension noun (neuter, imparisyllabic non-i-stem).
