The word "aardvark" begins with two As because it is derived from Afrikaans, a language spoken in South Africa, where the animal is found in the wild. In Afrikaans, the word for "earth" is "aarde," and the word for "pig" is "vark." The aardvark is a burrowing, nocturnal mammal that feeds on ants and termites, and its name in Afrikaans literally means "earth pig."

When the word "aardvark" was introduced into the English language in the 18th century, it was spelled with two As to reflect its Afrikaans origins. Over time, the word became established in English with its original spelling intact, and the double A at the beginning of the word has become a distinctive and recognizable feature of the word.
