Coronar con el lauro.
(2) If the first of two contiguous vowels after the accent is strong and the second is weak, they form a diphthong, as in amabais, temierais. But it is frequently dissolved with ease, since in many cases the vowels stood xxvi originally in separate syllables; thus amábades and temiérades were good forms down to the seventeenth century.
(3) If the first of two contiguous vowels after the accent is weak and the second strong, there is a diphthong usually indissoluble; e.g., injuria, limpio, continuo. Dissolution is possible, however, where u is the first vowel (as in continuo, estatua).
III. Combinations of Two Vowels before the Accent
(1) Two contiguous strong vowels before the accent naturally form two syllables; e.g., lealtad, roedor are properly trisyllabic. But synæresis is possible, especially where e is one of the vowels.
(2) If the first of two contiguous vowels before the accent is strong and the second is weak, they naturally form a diphthong; vaivén, peinado. They are regularly in distinct syllables, however, when the first vowel (except a) is part of a prefix, as in preinserto, prohijar, rehusado (prefixes pre-, pro-, re-). Nevertheless, synæresis is here permitted, and the diphthong is normal where a is the vowel of the prefix, as in airado, ahumado.
(3) Usage varies when of two contiguous vowels before the accent the first is weak and the second strong. The derivative follows the simplex; thus the i and the a are in separate syllables in criador and criatura because they so stand in criar, they form one syllable in cambiamiento because they do so in cambiar. But synæresis is always possible where the diphthong does not already exist.
(4) If both the contiguous vowels before the accent are weak, they naturally form a diphthong, as in ciudad, cuidado. Derivatives of words of variable syllabification may imitate their simplex: thus viudo may be either dissyllabic or trisyllabic (cf. [I, rule 7]) and viudez has the same liberty.
IV. Combinations of Three or more Vowels
(1) Three contiguous vowels with the accent on the first. These offer two possible forms of combinations, viz., one of two vowels with the first accented plus one of two vowels after the accent. To these apply the rules already stated. Thus in lóaos we have óa in two syllables according to [I, rule 1], and ao which may be in two syllables by [II, rule 1], therefore all three vowels may be in separate syllables. So, too, in iríais we have ía in two syllables by [I, rule 4], and ai which forms a diphthong by [II, rule 2], therefore the combination íai forms two syllables.
