(1) Two contiguous strong vowels after the accent naturally form two
syllables: e.g., _Dánao_, _héroe_, _temiéndoos_. Yet the poets usually
make diphthongs of them; e.g., Moratín:
Los hér[oe]s que la fama
Coronó de laureles,
and only exceptionally treat them as dissyllabic; e.g., Samaniego:
Cuando á un héròè quieras
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 _amab[ai]s_,
_temier[ai]s_. But it is frequently dissolved with ease, since in many
cases the vowels stood 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.,
_injur[ia]_, _limp[io]_, _contin[uo]_. Dissolution is possible, however,
where _u_ is the first vowel (as in _continuo_, _estatua_).
