| doublet (etymology) |
| Definition: Unique words that derive from borrowing and re-borrowing the same foreign word. Note: three such words — e.g., cattle, chattel, and capital — are called triplets. |
| Example:
(1) The words frail and fragile are doublets that derive from the Latin fragilis, fragile; (2) aperture and overture (from the Latin aperire, to open); and (3) thesaurus and treasure (from the Greek thesauros, a storehouse). |
| Etymology: The word derives from the French doublet, which was coined as a diminutive of double. |
