road: [OE] Road comes from the same ultimate source as ride – and indeed in the Old English period it meant either simply ‘riding’ or ‘hostile incursion on horseback’ (a sense preserved in inroads [16] and also in raid, which is historically the same word as road). By the 14th century the sense ‘sheltered anchorage’ (now represented by the plural roads) had emerged, but the central modern meaning ‘track for traffic’ did not put in an appearance until the late 16th century (hitherto the main words for expressing this concept had been way and street). => inroads, raid, ride[road etymology, road origin, 英语词源]
