- bedridden (adj.)
[bedridden 词源字典]
- also bed-ridden, mid-14c., from adjectival use of late Old English bæddrædæn "bedridden (man)," from bedrid, from Old English bedreda, literally "bedrider, bedridden (man)," from bed + rida "rider" (see ride (v.)). Originally a noun, it became an adjective in Middle English and acquired an -en on the analogy of past participle adjectives from strong verbs such as ride.[bedridden etymology, bedridden origin, 英语词源]
