| 词汇 | piggy bank |
| 词源 | piggy bank. Though piggy bank’s popularity over the years probably has something to do with the relation between hoard- ing or saving money and the pig’s supposed greediness, the main reason the child’s bank is called a piggy bank is simply because so many of the banks are made in the shape of pigs. They have been made in such shapes since at least 1909, though the first recorded use of the term piggy bank is in 1945. |
