_Consonantal rhyme_ is one in which all the letters, vowels and
consonants, are the same from the accented syllable to the end of the
word, e.g. _bruma--espuma_; _flor--amor_.
In consonantal rhyme both consonants and vowels should agree exactly
(_sonante--errante_); b and v can, however, rhyme together, since they
represent the same sound, e.g. _estaba--esclava_; _haba--clava_.
The following are a few general rules for consonantal rhyme.
A word should not rhyme with itself. Sometimes, however, a simple word
rhymes with a derivative (_menor--pormenor_) or two derivatives with
each other (_menosprecio--desprecio_).
The tenses of verbs which end in -aba, -ando, -áis, -éis; the present
and past participles of regular verbs; adverbs with the termination
-mente; verbal nouns ending in -miento, -ción, and other similar
endings,--should not rhyme together.
Words similar in sound and form but distinct in meaning may rhyme.
_son_ ('sound')--_son_ ('are')
If an unaccented weak vowel (i, u) precedes or follows a strong vowel
in the same syllable of a word, it is absorbed by the strong vowel,
and does not count in the rhyme. Therefore, _vuelo_ and _cielo_ rhyme;
also _muestra_ and _diestra_.
