Derivatives: -1. καῦμα `fire, heat, glow' (Il.) with καυματ-ώδης (Hp., Arist.), - ηρός (Str.), - ίας (Thphr.; of the sun) `burning, glowing', καυματίζω `burn, singe' (NT, Plu., Arr.). - 2. καῦσις ( ἔγκαυσις etc.) `burning' (IA.) with ( ἐγ-, κατα-)καύσιμος `inflamable' (Pl., X.; cf. Arbenz Die Adj. auf - ιμος 49f.). - 3. καῦσος m. `causus, bilious remittent fever etc.' (Hp., Arist.), from καῦσαι or rather with σο-suffix (Solmsen Wortforsch. 244, Strömberg Wortstudien 87f., Schwyzer 516); from there καυσία `Macedonian hat against the sun', καύσων `id.', also `heat, hot wind etc.' (LXX, NT, medic.; cf. Leumann Sprache 1, 207 n. 13), καυσώδης `burning, hot' (Hp., Thphr.), καυσόομαι, - όω `have causus, burn: heaten' (medic., NT, pap.) with καύσωμα `heating' (Gal.). - 4. καυ(σ)τήρ m. `burner, burning iron' (Pi., Hp.), f. fen. καυστειρῆς adjunct of μάχης (Il.), καμίνου (Nic.), from *καύστειρα (Schwyzer 474, Chantraine Gramm. hom. 1, 192; note the switching accent); καυτήριον `branding iron, brand' (LXX, D.

Origin: IE [Indo-European]X [probably] [595] * keh₂u- `burn'

Etymology: As καίω may stand for *κάϜ-ι̯ω (from where Att. κά̄ω; Schwyzer 265f.), all forms go back on καυ-, κᾰϜ- except ἔ-κη-α for *ἔ-κηϜ-α (often written with false - ει- in κείαντο etc.; Chantraine Gramm. hom. 1, 9; Att. κέαντος with metathesis). In *ἔ-κηϜ-α an old fullgrade root aorist is maintained (Schwyzer 745; prob. not from *ἔ-κηυ-σ-α); the full grade also in ep. κηλέος, κηώδης, and in Delph. κηυα, which shows a PGr. κηϜ- beside κᾰϜ-. - Only Baltic gives a possible connection in Lith. kū̃lės `Brandpilze, Flugbrand, Staubbrand des Getreides', kūlé̇ti `brandig werden', Latv. kũla `old, dry, grass of last year' (cf. Fraenkel Wb. s. v.); IE. zero grade kū- (\< * kuH-) beside fullgr. * keh₂us- in ἔ-κηϜ-α, zero grade *kh₂u̯- in *κάϜ-ι̯ω, καῦ-μα. Of course rather unncertain.
