The American Alligator
Occasionally a scientific binomial needs little or no translation or explanation. Today’s word, Alligator mississippiensis is a perfect example. First described by French zoologist François Marie Daudin in his most important treatise that covered 1100 reptiles, frogs and lizards, the 8 volume Natural History of Reptiles.Daudin described the species as Crocodylus. But even the word alligator needs no real translation-it is a mash-up of the Latin pronoun ille meaning that and lacertus, meaning a lizard. Yes, imagine the fear of seeing a real alligator for the first time and only being able to stammer out ‘that-Lizard!’ The word alligator entered English as alligater or alligarter around 1560. Mississipienses refers to the river, not the American state.
