- pianola (n.)
[pianola 词源字典]
- c. 1896, trademark name (1901) of a player piano, from piano, the ending perhaps abstracted from viola and meant as a diminutive suffix. The pianola's popularity led to a rash of product names ending in -ola, especially Victrola (q.v.), and slang words such as payola.[pianola etymology, pianola origin, 英语词源]
