anchor: [OE] English borrowed this word from Latin in the 9th century, but its ultimate source is Greek ágkūra (which goes back to an Indo- European base *angg- ‘bent’, also the source of angle and ankle). Originally it was spelled ancor, reflecting Latin ancora; the inauthentic h began to creep in in the 16th century, in imitation of the learned-looking but misguided Latin spelling anchora. => angle, ankle[anchor etymology, anchor origin, 英语词源]
