In final syllables the diphthongs ai, ei, oi, all appear as e.
In English, moreover, the vowel sounds tend to become diphthongs, so that the symbol for the simple sound tends to become the symbol for that combination which we call a diphthong.
Navarrese-Aragone~e has the diphthongs Ce, ue from tonic and, and adheres more strictly to them than normal Castilian doescuende (c b m i t e rn) huey (h d 1 e), pueyo (pb di U rn), yes (e s t), yeran (h r ii n t), while Castilian says conde, hoy, poyo, es, ryan.
On the other hand, Portuguese has a large n.urnber of strong diphthongs produced by the attraction of an i in hiatus or the resolution of an explosive into i: raiba (r a b I a),feira (fer i a), frito (f a c t u m), seixo (sax u m), osto (oct 0).
The Latin alphabet is used, with special signs to represent sounds borrowed from Slavonic, &c. All the unaccented vowels except e are pronounced as in Italian; e has the same phonetic value as in Old Slavonic (=French e) and is often similarly preiotized (= ye in yet), notably at the beginning of all words except neologisms. The accented vowels é and ó are pronounced as ea and oa (petra, rock, = peatra; morte, death, = moarte); they are written in full, as diphthongs, at the end of a word and sometimes in other positions.
Ai produced by a+i oC by a+a palatal consonant has for the greater part of the time bec9me an e in the modern language; factum has yielded fait, feit, and then fet, the last being the actual form; anus has given er alongside of a-ire, an, which are learned or semi-learned forms. Of, the two weak diphthongs and ud, the latter, as has heed seen, tends to become o clom in the atooic syll.sble, and is pronounced a quaranta has become coranta, then curanta.
It is stated, for example, that Gallego does not possess nasal diphthongs; still it may be conceded once for all that such a word as p 1 a n u s, which in Galician is written sometimes chau and sometimes c/ian, cannot be very remote from the Portuguese nasal pronunciation chao.
The only strong diphthongs of the spoken language are di, du (rather rare), ei, u-, -ia, oi, u, di, uu.
(7) The decay of all diphthongs; ai, oi, ei all become a monophthong variously written e and i (rarely ei), as in the dat.
Maintains the diphthongs ai and au, which in Hebrew have usually passed into e and o.
Like Umbrian also, but unlike Latin and Oscan, it has degraded all the diphthongs into simple vowels (Volscian se parallel to Oscan svai; Volscian deue, Old Latin and Oscan deivai or deiuoi).
