Etymology
Alfa comes from Greek alpha, the name of the first letter of the Greek alphabet. Greek itself took the name from a Semitic source, close to Phoenician aleph, which meant ox and named a similarly shaped early letter. Romanian borrowed the word as part of the shared European scientific and academic vocabulary, likely through French or Latin channels rather than directly from Greek.
