In linguistics, a homonym is one of a group of words that share the same pronunciation but have different meanings, whether spelled the same or not. A more restrictive definition sees homonyms as words that are simultaneously homographs (words that share the same spelling, regardless of their pronunciation) and homophones (words that share the same pronunciation, regardless of their spelling). The relationship between a set of homonyms is called homonymy. Examples of homonyms are the pair stalk (part of a plant) and stalk (follow/harass a person) and the pair left (past tense of leave) and left (opposite of right). A distinction is sometimes made between "true" homonyms, which are unrelated in origin, such as skate (glide on ice) and skate (the fish), and polysemous homonyms, or polysemes, which have a shared origin, such as mouth (of a river) and mouth (of an animal).
In non-technical contexts, the term "homonym" may be used (somewhat confusingly) to refer to words that are either homographs or homophones. The words row (propel with oars) and row (argument) and row (a linear arrangement of seating) are considered homographs, while the words read (peruse) and reed (waterside plant) would be considered homophones; under this looser definition, both groups of words represent groups of homonyms.
In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon.
The rule in the International Code of Zoological Nomenclature is that the first such name to be published is the senior homonym and is to be used (it is "valid"); any others are junior homonyms and must be replaced with new names. It is, however, possible that if a senior homonym is archaic, and not in "prevailing usage," it may be declared a nomen oblitum and rendered unavailable, while the junior homonym is preserved as a nomen protectum.
Similarly, the International Code of Nomenclature for algae, fungi, and plants specifies that the first published of two or more homonyms is to be used: a later homonym is "illegitimate" and is not to be used unless conserved (or sanctioned, in the case of fungi).
Dime si hoy
podrás besarme sin que pase el tiempo
sabes quien soy y quiero amarte sin pedir perdón
Sabes que ayer, volando juntos, nos llevaba el viento
Sabes amor, el suave ronroneo de tu piel
Parece que fue ayer, creí que nunca iba a amanecer,
soñaba con ver hacer la brisa fresca bajo el sol, no, no
no puede ser, hoy tengo un angel libre sólo para mi y ya no sé que hacer
con tanta vida en mi interior
Dime si hoy
podrás besarme sin que pase el tiempo
sabes quien soy y quiero amarte sin pedir perdón
Sabes que ayer, volando juntos, nos llevaba el viento
Sabes amor, el suave ronroneo de tu piel
Enseñame a sentir, sin preocuparme de nada más
tu voz me guiará por un paisaje para dos
Ayúdame a intentar, dibujar un mundo perfecto sin adiós
y así poder seguir, con este sueño entre tu y yo
Dime si hoy
podrás besarme sin que pase el tiempo
sabes quien soy y quiero amarte sin pedir perdón
Sabes que ayer, volando juntos, nos llevaba el viento
Sabes amor, el suave ronroneo de tu piel
Somos como el agua desbordándonos,
recorriendo juntos mares de ilusiones
descubriendo nuevas formas de amor
Dime si hoy
podrás besarme sin que pase el tiempo
sabes quien soy y quiero amarte sin pedir perdón
Sabes que ayer, volando juntos, nos llevaba el viento
Sabes amor, el suave ronroneo de tu piel
