oregano

The journey of 'oregano' into English is a story of Mediterranean borrowing. The word originates from Ancient Greek 'orīganon', a term for the aromatic herb. It passed into Latin as 'orīganum' and then into Spanish as 'orégano' before being adopted into English in the mid-18th century. While its Greek roots may poetically suggest "joy of the mountain," referring to the herb's bright appearance on hillsides, the modern English word carries no internally analyzable morphemes. Its meaning is fixed as the name for the specific culinary herb, a direct legacy of its path as a loanword.

The word is a simplex loanword. It entered English as a whole unit from Spanish 'orégano', which came from Latin 'orīganum', itself borrowed from Ancient Greek 'orīganon'. The Greek word is of uncertain origin but may be a compound of 'oros' (mountain) and 'ganos' (brightness, joy), though this etymology is not reflected in the modern English spelling.
