英文詞源
- optical
- optical: [16] Greek optós meant ‘visible’ (it was presumably related to ophthalmós ‘eye’, source of English ophthalmic [17], and belonged to the general Indo-European family of ‘eye’/‘see’- words – including English eye itself – that goes back to the base *oqw-). From it was derived optikós, which has given English optic [16] and optical. Optician [17] originated as a French coinage.
=> ophthalmic - optical (adj.)
- 1560s, from optic + -al (1). Of abstract art, from 1964. Related: Optically.
