I'm 99% certain Achilles is male.
According to a dataset of 449, the average Achilles is around 39 years old.
From the Greek Ἀχιλλεύς (Achilleus), which is of unknown meaning, perhaps derived from Greek ἄχος (achos) meaning "pain" or else from the name of the Achelous River. This was the name of a warrior in Greek legend, one of the central characters in Homer's Iliad. The bravest of the Greek heroes in the war against the Trojans, he was eventually killed by an arrow to his heel, the only vulnerable part of his body. This name was sometimes used as a personal name, and was borne by a few early saints, including a Roman soldier martyred with Nereus in the 1st century.
We use a combination of data from the internet, and our own Machine Learning models to make these predictions.
In a gist, we use a Machine Learning model trained on a diverse global dataset of 100m+ names, and use it to predict different traits for a person based on first name!
NameGuessr guesses a person's nationality, age, and gender based on their name. We also try to give insightful info around the name's origin, name meaning, and name pronounciation.
