英语词源
- knapsack
-
knapsack: [17] The -sack of knapsack is no doubt essentially the same word as English sack, but the knap- presents slightly more of a problem. The term was borrowed from Low German knappsack, and so probably knapprepresents Low German knappen ‘eat’ – the bag having originally been named because it carried a traveller’s supply of food.
- knapsack (n.)
- c. 1600, from Low German Knapsack (Dutch knapzak), probably from knappen "to eat" literally "to crack, snap" + Sack "bag" (see sack (n.1)).
