Ida

Short form of obsolete names beginning with Germanic īd "work", used for both sexes in medieval England. It was revived in the 19th century, partly mistaken for a Greek name, for the Mount Ida of classical mythology.

Two possible origins:

Borrowed from Japanese 井田 (Ida, “rice paddy by the well”).

Matronymic surname from the female given name Ida.

From Ancient Greek Ἴδη (Ídē).

Borrowed from Slovak Ida.

From Sanskrit इडा (iḍā).
