From Proto-Italic *swopnjom, derived from the root of somnus (“sleep”); possibly inherited from Proto-Indo-European *swópn-yo-m, from the root *swep- (“to sleep”).
Cognate with Sanskrit स्वप्न्यम् (svápnyam, “vision in a dream”), Lithuanian sapnỹs (“sleep, dream”), Old Church Slavonic съниѥ (sŭnije, “dream”), Tocharian B sänmetse (“in a trance”).
By surface analysis, somnus (“sleep”) + -ium (nominal derivational suffix).
somnium n (genitive somniī or somnī); second declension
Second-declension noun (neuter).
