tlacuache

The tlacuache is the common opossum of Mexico and Central America, the only marsupial native to North America north of Panama. It was already well known to the Nahua people when Hernán Cortés arrived in 1519. The animal's habits, its nocturnal omnivory, its convincing performance of death when threatened, and its pouch-bound young, made it one of the stranger creatures in Nahua natural history.

The Nahuatl name was tlacuatzin, from the verb tlacua meaning to eat or to gnaw, plus the diminutive honorific suffix -tzin. The suffix did not signal smallness so much as affectionate specificity, the same ending attached to revered figures and beloved animals. Spanish speakers in colonial Mexico shortened tlacuatzin to tlacuache, dropping the Nahuatl suffix and reshaping the final syllable to fit Spanish phonology.

Francisco Hernández, physician-naturalist to Philip II of Spain, documented the tlacuache in his natural history of New Spain, completed in the 1570s and published in Madrid in 1628. He noted both the pouch and the apparent resurrection behavior, playing dead so convincingly that observers believed it had died. European naturalists were fascinated: the opossum was the first marsupial most of them had encountered, and the Nahuatl name entered European scientific correspondence through his text.

Today tlacuache is the standard Mexican Spanish word for opossum, used in wildlife biology, folklore, and everyday conversation. The animal appears in Mexican proverbs about cunning and survival, and tlacuache is a mild colloquial term for someone who avoids confrontation by feigning helplessness. The Nahuatl root, nearly five centuries after the Conquest, still names the animal in the country where both the language and the creature originated.
