noun
person fallen sick by the wayside
A somewhat formal or literary term for someone who has become ill while traveling and is found by the roadside. Not an everyday word; more likely encountered in news reports, historical contexts, or legal discussions about aid to such persons.
警察は行路病者を保護し、病院に搬送した。
The police took custody of a person who had fallen ill by the roadside and transported them to a hospital.
Compound of 行路 (kōro, 'road; journey') and 病者 (byōsha, 'sick person'). The exact historical derivation is uncertain, but the term appears in legal and social welfare contexts from the early modern period onward.
