- speedometer (n.)
[speedometer 词源字典]
- 1904, from speed + -meter. A Germanic-Greek hybrid and thus much execrated.
[T]he ancient Greeks & Romans knew what speed was, & yet no-one supposes they called it speed, whence it follows that speedo- & speedometer are barbarisms. [Fowler]
The correct classical formation is tachometer.[speedometer etymology, speedometer origin, 英语词源]
