Whether through the Iberian languages or by other routes, such as the technical vocabulary borrowed by various European languages during the adoption of Arab mathematics and science, a number of English words contain the Arabic definite article. These include "alcove, alcohol, albatross, alfalfa, algebra, algorithm, alchemy, alkaline, alembic, elixir, artichoke, acequia, adobe, aniline, apricot, aubergine, azimuth," and the names of stars such as "Algol".
