Etymology

The word "bilingual" originates from Latin roots. The prefix "bi-" (meaning "two") combines with "lingua" (meaning "tongue" or "language"), reflecting the concept of dual-language ability. The suffix "-al" turns it into an adjective. Historically, "lingua" evolved into modern Romance language terms like "lengua" (Spanish) and "lingua" (Italian), retaining its core meaning. The word’s structure logically mirrors its definition—"two languages."
