Forms: α. 35 þilke, 37 thilke, 45 þylke, þilk, 47 thylke, 5 thylk, (6 thailk), 4 thilk. β. 35 pulke(ü), 5 þulk, 45 þelke. γ. 35 þike, 4 þyke, þeke, þuke, 45 thike, thyke, theke, 5 thik, 6 þieke; 9 dial. thik, thic, thick, thek, thuck, thicky. [ME. þilke, known a. 1300; app. f. þe, THE + ilce, ILK same, meaning the or that same; in some of the quots. þe ilke or þet ilke occurs as a MS. variant.
This analysis suits the form þilke, but does not explain the early southern þūlke and the Kentish þelke, which naturally indicate an OE. *þylce. Can there have been a confusion in the south between þilke and late OE. þylc for þyllic, THELLICH?
(Thick is in dialect use from Cornwall and Hants to Worcester and Hereford; and also in Pembroke, Glamorgan, and Wexford. In many parts it has also the form thicky, thickee, or thicka. It generally means that, but in some parts this, in which case it is contrasted with thuck, thock, or thack = that. It is sometimes indefinite, and has to be made definite, as thick here, this, thick there, that. In Somerset and Dorset, thick and theäse are used only of individual shaped things, as a man or tree, while that and this are used of formless substances in the mass, as flour, milk, marble. See Eng. Dial. Dict.)]
