Comments:Derived from PT *jāĺ 'young, green vegetables' (OUygh. jaš, MK jaš, Turkm. jāš, see ЭСТЯ 4, 162, EDT 975, 976, Федотов 2, 134, Stachowski 93). This root is often mixed with homophonous *jāĺ 'tear' and *jāĺ 'age, year', see ЭСТЯ 4, 161-164 (all three roots have different Altaic etymologies). Turk. > Mong. jasil 'buckthorn' (Clark 1980, 41).
Comments:VEWT 287, TMN 3, 640-642, EDT 708-9, ЭСТЯ 3, 66-68, Лексика 60, 604, Stachowski 165. In most languages the root also means 'sky'. Turk. > Hung. kék 'blue', see Gombocz 1912.
Comments:ЭСТЯ 4, 161-163, EDT 975-976, VEWT 192 (one of several *jāĺ roots). Within Turkic interacts actively (in fact almost completely merges with *jāĺ 'green' and *jāĺ 'young' - but all three roots, and, additionally, *jāĺ 'tear' and *jāĺ 'age' - seem to have different Altaic origins.
Comments:VEWT 192, EDT 975-976, Ашм. VII, 32, ЭСТЯ 4, 161-163 (because of external evidence should be distinguished both from *jāl' 'age' and *jāl' 'fresh, green').
Karakhanid:čikin / čekin 'a plant growing among the vines and eaten by cattle' (MK)
Tatar:čɛkɛn 'corn cob' (< Chuv.?)
Middle Turkic:čekin 'greens, grass; a weed on rice fields, with black seeds and sharp awns' (Pav. C., Sangl.), čekil-dam 'tulip bulb; a root similar to wild garlic' (Pav. C., for dam cf. Uzb. dam 'pungency, bitterness' < Pers.)
Uzbek:čakalak 'bush thicket' (or perhaps to PT *čeke-t?)
Khakassian:sǝgen 'dry grass'
Chuvash:čakan 'reedmace'
Kirghiz:čeken 'рогоз широколистый'
Bashkir:sɛkɛn 'corn cob' ( < Chuv.?)
Karakalpak:šigin 'weed growing on rice fields, куриное просо', šigildik 'reed'
Comments:VEWT 111, EDT 415, Рас. ФиЛ 277, Егоров 316. Chuv. čakan, despite Дмитриева 1997, 52-53 and Róna-Tas, is not connected with *jeken 'reed' (v. sub *dék`à). Cf. other grass names: Chuv. čiken kurъkǝ 'geranium' (according to Ашм., grass helping from colics - Дмитриева 1997, 56); śikka kurъkǝ 'camomile' (according to Ашм. it hosts a plantlouse, to summon which the children say "śikka!" - Дмитриева 1988, 51); Uygh. čigä 'plant fibre, wild hemp (VEWT), Yak. sige 'тальниковые стружки, лыко'. Tuva sigen 'hay' (Tuva), (Tof. 'grass') has an irregular s-, so perhaps should be regarded as borrowed from Khak.
Comments:ЭСТЯ 4, 162, VEWT 192 (one of several *jāĺ roots; within Turkic hardly distinguishable from *jāĺ 'green vegetables; green', but historically different).
