📚 Etymology▼
The word comes from the Latin 'Sirena,' which itself derived from the Greek word 'Seirēn.' In Greek mythology, the Seirēns were dangerous creatures who lured sailors to their doom with their beautiful, captivating music. The modern meaning of the loud warning sound (siren/alarm) was adopted because the device produces a powerful, attention-grabbing sound, much like the mythological creature's song.
First recorded: Ancient Greek/Roman texts, adopted into Spanish during the medieval period.

Frequently Asked Questions
Why does one word, 'sirena,' mean both a magical creature and a loud alarm?
They are connected through sound! The mythical Sirens were known for their powerful, irresistible singing that commanded attention. When the first mechanical devices were invented to make a loud, attention-grabbing warning sound, they were named 'sirenas' after the mythological beings.
Is 'sirena' a common word for a man, too?
No. 'Sirena' is always female. If you need to talk about a mythical creature that is half-man and half-fish, the correct Spanish word is 'sireno' or 'tritón' (Triton).
