u in Middle English documents from the area. Some words with the sound were borrowed into London Middle English, where the unfamiliar was substituted with : gild < gyldan, did < dyde, sin < synn, mind < mynd, dizzy < dysiġ, lift < lyft etc. show the normal (Anglian) development; much < myċel shows the West Saxon development; merry < myriġ shows the Kentish development; bury < byrġan has its spelling from West Saxon but its pronunciation from Kentish; busy < bysiġ, build < byldan, buy < bycġan have their spelling from West Saxon but their pronunciation from Anglian. Some apparent instances of modern e for Old English y are actually regular developments, particularly if the y is a development of earlier (West Saxon) ie from i-mutation of ea, as the normal i-mutation of ea in Anglian is e; for example, stern < < , steel < stȳle < (cf. Old Saxon stehli). Also, some apparent instances of modern u for Old English y may actually be from the influence of a related form with unmutated u: sundry < syndriġ, influenced by sundor "apart, differently" (compare to sunder and asunder).
