Origin: IE [Indo-European] [1003] *sreu̯- `flow, stream'

Etymology: The the themat. root-present ῥέω (\< *ῥέϜω; cf. ῥόϜος a.o. above) agrees Skt. srávati `flow', IE *sréu̯-eti. Also to other forms there are exact agreements outcide Greek, of which the age is however uncertain because of the strong productivity of the relevent form-categories: ρόος = Skt. srava- m. `the flowing'; cf. OCS o-strovъ, Russ. óstrov `island' (prop. "surrounded by stream(s)"); ῥοή = Lith. sravà f. `flowing, flow of blood, menstruation'; cf. Skt. giri-sravā f. `mountainstream', ῥύσις = Skt. srutí- f. `way, stret' (but e.g. vi-sruti- `flowing out'; cf. Liebert Nom. suffix -ti- 39); ambiguous Arm. aṙu `canal'; ῥυτός = Skt. srutá- `flowing'; cf. Lith. srùtos pl. (dial. -tà sg.) f. `liquid manure, (animal)urine'; (ἐϋ) - ρρεής: Skt. ( madhu) - sravas- m. "dripping of honey", plantname (lex.). Over aginst the neuter ῥεῦμα (IE *sreu̯-mn̥) stands in Balto-Slav. a corresponding masc., e.g. Lith. sraumuõ, gen. -meñs `rapid' (IE *srou̯-mon-); similar Thrac. rivername Στρυμών. An m-suffix also in Germ., e.g. OWNo. straumr ' stream' (IE *srou̯-mo-), in Celt., e.g. OIr. sruaim `stream' and in Alb. rrymë `stream' (Mann Lang. 28, 37). -- Genetic connection has also been supposed between Dor. aor. ἐ-ρρύᾱ and Lith. pret. pa-srùvo `flowed' (\< *-āt; Schwyzer 743 w. n. 11 a. lit.), also between Ion.-Att. ἐρρύη and Lith. inf. sravė́ti. Formally identical are also the futures ῥεύσομαι (- σω) and Skt. sroṣyati. Further the Greek and Sanskrit as well as the Balt. verbal systems go different ways. -- Further forms w. lit. in WP. 2, 702 f., Pok. 1003; Fraenkel s. sravė́ti, Vasmer s. strúmenъ; older lit. also in Bq. -- Vgl. ῥώομαι.
