ly, e.g. _perdon--espiro_; _azul--tu_.

In words accented on the antepenult (_esdrujulas_) or on a preceding
syllable, only the accented syllable and the final syllable count for
purposes of assonance. Therefore, _fabula_ and _lagrimas_ assonate in
a-a; _tremulo_ and _vertigo_ assonate in e-o.

Words accented on the last syllable (_agudas_) cannot assonate with
words accented on the penult (_llanas_), or with those accented on the
antepenult (_esdrujulas_) or upon any preceding syllable.

In words _llanas_ or _esdrujulas_ the assonance is of two vowels only.
In diphthongs the accented vowel only is considered if the diphthong
occur in an accented syllable. Therefore, _verte_ and _duermes_
assonate in e-e; _baile_ and _parte_ assonate in a-e.

Words _llanas_ may assonate with words accented on the antepenult
(_esdrujulas_). Therefore, _portico_ and _olmos_ assonate in o-o.

For purposes of assonance little use is made of words accented on a
syllable preceding the antepenult.

In a final accented or unaccented syllable u and i are absorbed, for
purposes of assonance, by a preceding or following a, o, or e.
Therefore, _sabia_ and _gratia_ assonate in a-a; _igual_ and _mar_
assonate in a, _pleita_ and _pliega_ assonate in e-a.

If in assonance a weak vowel is united in a diphthong with a strong
vowel, the assonance is called _compound assonance_, e.g.
_guarda--fatua_.

Assonance between two single vowels is called _simple assonance_, e.g.
_sangre--trae_.

This distinction is of little value, however, for verses in simple and
compound assonance alternate constantly.

In the case of two strong vowels forming a diphthong after an accented
syllable, the following rules apply.

a in a final unaccented syllable predominates over a preceding or
succeeding o in the same syllable. Therefore, _Astarloa_ and _Danao_
assonate in a-a.

a in a final unaccented syllable predominates over a preceding or
following e in the same syllable. Therefore, _corporea_ and _rosea_
assonate in o-a.

o in a final unaccented syllable predominates over a preceding e in
the same syllable. Therefore, _oleo_ and _erroneo_ assonate in o-o;
but o in a final unaccented syllable is dominated by a following e in
the same syllable, and the e counts in the assonance. Therefore,
_heroe_ and _veces_ assonate in e-e.

When two weak vowels (i, u) are united in a diphthong, the second
predominates. Thus _triunfo_ and _chulo_ assonate in u-o; _cuido_ a
