Vowel Changes Changes : qualitative (o-a), quantitative (i-i:). Dependent – a sound could change under the influence of the near standing sounds or a sertain type of syllables. Independen t – they affected sounds in all positions. Long vowels tend to become closer. Short vowels chanced into more open. (nochd –nahts – nacht; Mater – modor –mother). Independent. ablaut. a-i, o-a, Ø- Ø. Qualitative ablaut –e-o (нести-ноша). Quantitative ablaut - e – Ø (берубрал). Dependent changes. Mutation . e-i, u-o. (ego-ic, hurnan-horn). The PG short [a] and the long [a:] underwent similar alterations in Early OE: they were fronted and, in the process of fronting, they split into several sounds. The principal regular direction of the change - [a]> [ae:] and [a:]> [ae] - is often referred to as the fronting or palatalisation of [a, a: ]. The other directions can be interpreted as positional deviations or restrictions to this trend: short [a] could change to [o] or nasal [a] and long [a:] became [o:] before a nasal; the preservation of the short [a] was caused by a back vowel in the next syllables (sometimes [a] occurs in other positions as well, e.g. OE macian, land, NE make, land). 4.Development of Diphthongs The P C diphthongs [ ei, a i, iu, eu, a u] - under went r egular independent cha nges in Ear ly OE. The diphthongs wi th the i -glide were monophthongised into[i:] and [a :]; the diphthongs in -u wer e reflected as lon g diphthongs [io:], [eo: ] and [ea:]. A+i=a: s tains-s tan, e+i=i: reisan -risan, a+u=ea: auso -eare, e+u=eo:kiusan-ceosan, i+u=io: diups-deop. 5. Old English Consonant s ys tem. The s ys tem c ons is ted of s evera l correla ted sets of c onsona nts. All the c onsona nts f ell into noise c ons ona nts a nd s onorants. The noise con sonants were s ubdivided into plos ives a nd frica ti ves ; plos ives were fur ther differentia ted as voiced and voic eless . The fr ica ti ve c onsona nts wer e a lso s ubdivided into voic ed a nd voic eless; in this set, howe ver , s onor ity wa s merely a phonetic difference between a llophones . The mos t universa l dis tinc ti ve fea ture in the consonant s ys tem was the difference in length. Dur ing the entir e OE per iod long con sona nts are believed to ha ve been opposed to s hor t on es on a phonemic level; the y wer e mos tly dis tinguis hed in inter voca l pos ition. S ingle a nd gemina ted (long) c onsona nts are found in identica l phonetic conditions. In fina l position the qua ntita ti ve oppos ition was irr eleva nt a nd the second letter , whic h wo uld indica te length, wa s often lac king, e, g. OE man a nd eal are identica l to mann, eall. 2. P G ha d th e fo l lo wi n g two s e ts o f fr ic a ti ve c o ns ona n ts : vo ic e les s [ f , 0, x, s ] a nd vo i c e d [ v, ð , y, z] .

Nasal s onorants were regular ly los t before fr ica ti ve c onsona nts ; in the process the preceding vo wel was pr oba bly nasa lised a nd length ened. Fr ica ti ve c onsona nts c ould be dropped between vowels and before some plos ive consonants; these losses were acc ompanied by a c ompensa tor y lengthening of the preceding vo wel or the fus ion of the pr eceding a nd s ucceeding vo wel into a diphthong . We s hould als o men tion the loss of semivo wels and c onsona nts in uns tressed fina l s yllables. [j] was regular ly dr opped in suffix es a fter produc ing va r ious c hanges in the r oot: pa la ta l muta tion of vo w els , lengthening of c onsona nts a fter shor t vowels.
