Did you know?

The Italian word fante (from Latin infans, “infant, child”) originally meant “child,” later “youth, boy,” and then “servant.” In the 14th century, fante also took on the sense “foot soldier.” In Renaissance times, the fanteria, foot soldiers collectively, became a significant branch of arms, and the Italian word infanteria, was borrowed into English in the 1500s.

Word Origin

In the Middle Ages in France, a young soldier from a good family who was not yet a knight was called enfant, which means "child."

Later, Italian foot soldiers as a group became known as infanteria, which was borrowed into French as infanterie and into English as infantry.
