(Plu., Poll.); further perh. κρυερός `horrible, lugubrious' (Hom., Hes., Ar. in lyr.), `icy-cold' (Simon., Ar. in lyr.); cf. below. - Beside κρύος there are as independent formations: 1. κρῡμός m. `icy cold, frost, horror' (Ion., trag., hell.) with κρυμώδης `icy-cold' (Hp., Ph., AP), κρυμαλέος `id.' (S. E.; Debrunner IF 23, 22, Chantraine Formation 254), κρυμ-αίνω `make cold' (Hdn.), - ώσσω `be rigid from cold' (Theognost.). -- 2. κρύσταλλος s.v.

Origin: XX [etym. unknown]

Etymology: The wordgroup has cognates in diff. languages. On κρύσταλλος, which is Pre-Greek, s.v. The word is sonnected (Chantraine Formation 247, Schwyzer 484) with Lat. crusta `bark, crust'. However, this is wrong as the Latin word has a quite different meaning: `the hard surface of a body, the rind, shell, crust, bark' which protects it' (Lewis and Short); so it has nothing to do with cold; it is used of flumen, indicating a covering or crust of ice, but this is an incidental use, a metaphor, not the central aspect of the meaning. The word, then, has nothing to do with words for `cold, ice'. (Its etymology with κρύος must therefore be given up; there is no other proposal.) Further one connects Toch. B krost, A kuraś etc. `cold' (Duchesne-Guillemin BSL 41, 155 f.), but the -o- is difficult. One assumed for crusta the zero grade of an s-stem (so this is now wrong or irrelevant); beside it one proposed a full grade of the suffix in IE. *kruu̯-es- (?), Gr. κρύ-ος and in Latv. kruv-es-is `frozen mud'. Now *kruu̯-es- is not an admitted IE formation. It may have been * kruh₁-es-. [Not, with Frisk, to the word for `blood' Lat. cruōr \< * kreuh₂-ōs, Gr. κρέ(Ϝ)ας \< *kreu̯h₂-s-, s. v.] - With κρῡμός agrees Av. xrū-ma- `horrible'; but this word is analysed as * kruh₂-mo- and connected with the group of `blood' (above). One compared κρύος: κρῦμός with θύος: θῡμός, but the implication is not clear. The often assumed basic forms *κρύσ-ος, *κρυσ-μός are improbable (Frisk; does Chantraine accept this?) - κρυερός reminds of Skt. krūrá-, Av. xrūra- `wounded, raw, bloody, horrible', which points to * kruH-ro- (and Lat. crūdus `raw', if from * crūrus). κρυερός may have been rebuilt after the adj. in - ερός, but it can as well be an independent derivation from κρύος; cf. Bloch Sprachgesch. u. Wortbed. 23 n. 22. It might continue * kruh₁-er- (reconstructed above). Chantraine rejects the connection with `blood', as it would not fit semantically (but I think it fits very well) or formally. - A verbal * kreus- appears in Germanic, e.g. OWNo. *hrjósa, pret. hraus `shiver' with the zero grade verbal noun OHG hroso, -a `ice, crust'. On OIc. hrjósa see De Vries Wb., who denies that it has to do with cold or ice. - [Kluge<sup>22</sup> s.v. Kruste derives it from `verkrustetes Blut', which must be wrong, s. above.].
