dial. and Sc. Also chiller, chuller, churl (Jam.), choler. [perh.:OE. ceolur, ceolres throat, cogn. w. OHG. kelur str. masc.:OTeut. type keluro-, kelro-, from same root as kelôn-, whence OHG. chela (mod.G. kehle), OE. ceole (see CHEL). For the form, cf. OE. weolur lip, OS. lepor lip. The variant chiller might go back to the oblique form, genitive *cielr-es (see Sievers Ags. Gr. 75 Anm. 3). But the late appearance of the word is an element of difficulty; and it is not impossible that it may be related to cholle JOWL.]
