Etymology
The identification of the first form, which occurs in a list of early gifts to the nuns of Barking, is not certain. If it is correct the first element is a personal name Gislhere , with later t de- veloping between the consonants s and l . Cf. Bülbring, Altenglisches Elementarbuch , § 535. The form Gistel - developed to Yistle - and Istle -. The occasional development of earlier Is (s )leworth to Thistleworth is curious and so is the modern pronunciation with initial [aizəl] rather than [isəl].
