Origin: XX [etym. unknown]

Etymology: On πιεζ-έω as innovation beside older πιέζ-ω cf. κυρ-έω beside κύρ-ω a.o. (Schwyzer 721). Also πιάζω is an innovation (after the verbs in - άζω; perh. also phonet. explainable; s. Schwyzer 244 w. lit., a.o. Wackernagel IF 25, 336f. = Kl. Schr. 2, 1032 f.). -- Not certainly interpreted. Great semantic and phonetic similarity shows Skt. pīḍáyati `squeeze, press, hurt', which stands first for * pizd- and would give Gr. *πίζω. For it πιέζω after ἕζω (Schwyzer 721 n. 5)? Diff., very hard, Kuiper Acta Or. 12, 227f.: πιέζω from *pii̯es-dō as full grade of * pis-d- in Skt. pīḍ-. Further combinations hypothetic: * piz-d- from * pis-d- as d-enlargement of IE * pis- in Lat. pīnsō `pound, crush' (Fick, Curtius a. A.; cf. πτίσσω). -- Earlier (Brugmann, Osthoff etc.; s. Bq s.v. and WP. 2, 486 [Pok. 887]) from *(e)pi-sed-i̯ō resp. *( e)pi-zd- (\> pīḍáyati) prop. *"sit upon" = `squeeze' explained; against this Kuiper l.c. and Mayrhofer s.v. w. rich lit. and many details.
