several (adj.)

early 15c., "existing apart," from Anglo-French several, from Middle French seperalis "separate," from Medieval Latin separalis, from Latin separ "separate, different," back-formation from separare "to pull apart," from se- "apart" (see secret (n.)) + parare "make ready, prepare" (from PIE root *pere- (1) "to produce, procure"). Meaning "various, diverse, different" is attested from c. 1500; that of "more than one" is from 1530s, originally in legal use. Related: Severalty. Jocular ordinal form severalth attested from 1902 in American English dialect (see -th (2)).

Here we are all, by day; by night we're hurled

By dreams, each one into a several world
