Development of diphthongs

Development of monophthongs

Qualitative vowel changes.

The OE close labialized vowels [y] and [y:] disappeared in Early ME, merging with various sounds in different dialectal areas. The vowels [y] and [y:] existed in OE dialects up to the 10^th c., when they were replaced by [e], [e:] in Kentish and confused with [ie] and [ie:] or [i] and [i:] in WS. In Early ME the dialectal differences grew. In some areas OE [y], [y:] developed into [e], [e:], in others they changed to [i], [i:]; in the South-West and in the West Midlands the two vowels were for some time preserved as [y], [y:], (Slide 8) but later were moved backward and merged with [u], [u:], e.g. OE fyllan – ME (Kentish) fellen, (West Midland and South Western) fullen, (East Midland and Northern) fillen – NE fill. In Early ME the long OE [a:] was narrowed to [o:]. This was and early instance of the growing tendency of all long monophthongs to become closer, so [a:] became [o:] in all the dialects except the Northern group, e.g. OE stān – ME (Northern) stan(e), (other dialects) stoon, stone – NE stone. The short OE [æ] was replaced in ME by the back vowel [a], e.g. OE þǽt > ME that [Өat] > NE that. (Slide 9)

OE possessed a well developed system of diphthongs: falling diphthongs with a closer nucleus and more open glide arranged in two symmetrical sets – long and short: [ea:], [eo:], [ie:] and [ea], [eo], [ie]. Towards the end of the OE period some of the diphthongs merged with monophthongs: all diphthongs were monophthongised before [xt], [x’t] and after [sk’]; the diphthongs [ie:], [ie] in Late WS fused with [y:], [y] or [i:], [i]. In Early ME the remaining diphthongs were also contracted to monophthongs: the long [ea:] coalesced (united) with the reflex of OE [ǽ:] – ME [ε:]; the short [ea] ceased to be distinguished from OE [æ] and became [a] in ME; the diphthongs [eo:], [eo] – as well as their dialectal variants [io:], [io] – fell together with the monophthongs [e:], [e], [i:], [i].
