hi , teacher
whats the meaning of siren here, please
-Where has that siren taken john?
-Where is that siren? Siren!
-Come out, siren! Come out now!
Note that, where I come from, 'siren' is not interchangeable with 'mermaid' - that mythical sea-going creature with the bottom half of a fish (mentioned in another thread). The word 'siren' is used almost always in idioms that refer to classical mythology (for example, 'siren voices' are voices - perhaps metaphorical 'voices' - that tempt someone away from what they know is right). It's also used to refer metaphorically to a woman who's attractive (and probably therefore sexually tempting). For example, The Times this morning has a feature on 'screen sirens'.
PS I'm usually quite quick to recognize cognates (=related words in different languages) but the first time I heard the Spanish word sirena it took me quite a while to find out that it meant 'mermaid'.
"Siren" can be used to describe any female temptress who can mesmerize a man unexpectedly, often against his will. See, for example, how easily these sirens distracted three good ol' country boys who were on the run from the law.
