How to Say Mermaid in Spanish

Sirena · noun · see-REH-nah

Mermaid in Spanish is 'sirena,' a word that also means siren (as in an emergency vehicle's alarm or a warning device). This dual meaning comes from Greek mythology, where sirens lured sailors with their voices. Context makes the meaning clear—a sirena in a fairy tale is a mermaid, while a sirena on an ambulance is a siren.

Say see-REH-nah with stress on the second syllable. The word has three clear syllables and no difficult sounds for English speakers.

La niña se disfrazó de sirena para la fiesta de disfraces.

The girl dressed up as a mermaid for the costume party.

Avoid These Mistakes When Using Sirena

Confusing the two meanings

Incorrect: La sirena del bombero es muy bonita. (unintentionally meaning a mermaid firefighter)

Correct: La sirena del camión de bomberos es muy fuerte. (fire truck siren)

Without enough context, 'sirena' can be ambiguous. Adding descriptive elements (del camión, de emergencia) clarifies when you mean the alarm device rather than the mythical creature.

Using 'mermaid' or creating 'mermaida'

Incorrect: Vi una mermaida en la película.

Correct: Vi una sirena en la película.

There is no Spanish word 'mermaida.' The English word 'mermaid' does not transfer into Spanish. The only correct term is 'sirena.'

Common Questions About Mermaid in Spanish

Why does 'sirena' mean both mermaid and siren?
Both meanings trace back to the Greek Sirens (Σειρῆνες), mythological beings who lured sailors to their doom with enchanting voices—the mythological creature evolved into the mermaid image over time, while the warning device was named 'sirena' because its loud wailing sound metaphorically resembles the irresistible call of the mythological Sirens.
What is 'La Sirenita' in Spanish?
La Sirenita (The Little Mermaid) uses the diminutive suffix '-ita' added to 'sirena' to create an affectionate 'little mermaid,' and this is the official Spanish title of both the Hans Christian Andersen fairy tale and the Disney animated film that adapted it.
How do you say 'merman' in Spanish?
A male mermaid is called 'tritón' in Spanish (from Triton, the Greek sea god), not 'sireno'—though colloquially some speakers create the masculine form 'sireno' by analogy, 'tritón' remains the traditional and more widely recognized term for a male merfolk.
