owed by a strong vowel after the accented
syllable, they form a diphthong, e.g. _histor^i^a, ans^i^a_.

Ex. _De la brisa nocturna al tenu^e soplo_, p. 192, LXXV, l. 6.

The diphthong may, however, be dissolved, e.g. _estatu|a, tenu|e,
nadi|e_.

3. TRIPHTHONGS AND COMBINATIONS OP THREE OR MORE CONTIGUOUS VOWELS

If three vowels belonging to the same word are contiguous, one of them
must be accented. There are then three possible arrangements.

(i) Three contiguous vowels of a word with the accent on the first,
e.g. _traeos_.

(ii) Three contiguous vowels of a word with the accent on the second,
e.g. creia, _buey_.

(iii) Three contiguous vowels with the accent on the third, e.g.
_rehui_.

Each of the above arrangements has two combinations of accented and
unaccented vowels to which the rules for diphthongs may be applied. In
(i) there will be a combination of two vowels with the first accented,
plus a combination of two vowels after the accent. In _traeos_, for
example, the a and e would probably be in separate syllables by b (1)
(a), and eo would probably form a diphthong by c (1). _Traeos_ would,
then, probably be a dissyllable.

In (ii) there will be a combination of two vowels with the accent an
the second, and one of two vowels with the accent on the first. In
creia, for example, the e and i would be in separate syllables by b
(2) (b), and the i and a would probably be in separate syllables also
by b (2)(a). Therefore, _creia_ would probably be a trisyllable. In
_cambiaos_ the i and a might form one syllable or two by b (2) (_d_),
and the a and o would probably be in separate syllables by b (1) (a).
Therefore, in _cambiaos_ the combination iao might form a dissyllable
or a trisyllable.

In (iii) there will be a combination of two vowels before the accent,
and one of two vowels with the second accented. In _rehui_, for
example, the e and u might be in the same syllable by a (1), or in
separate syllables by dieresis by a (1) (a), and the u and i might be
in separate syllables or not by b (3) (b). Therefore, _rehui_ might be
a monosyllable, a dissyllable, or a trisyllable.

Other combinations of three vowels may be analyzed in a similar way,
as may also combinations of more than three vowels, e.g. _creiais_,
etc.

B. SYNALEPHA

Between the contiguous vowels of separate words there may occur
synalepha (which corresponds to diphthongization within a word), or
hiatus (which is similar to diaeresis wi
