Choosing between bank · shore · coast · beach

A bank is the ground at the edge of a river, a stream, or a lake. The shore is the land at the edge of the sea or a large lake, where it meets the water. The coast is the whole area of land beside the sea, seen from far away or on a map: a town on the coast. A beach is the sand or small stones at the edge of the sea, where people swim and sit.

Usage

Money is in the bank; you go to the bank and open an account at or with a bank. The people who work there are bank staff or bank clerks, and the person in charge of a branch is the manager. Bank holiday is British for a public holiday and has nothing to do with banks being open.

Common mistakes

In several languages a look-alike word means a seat; English bank never does.

Bank is countable and needs the or a.

Word origin

Both main senses go back to an old Germanic word for a bench or a raised edge. The money sense came through Italian, where a banca was the bench or table at which a money changer did business; the river sense came from an old Scandinavian word for a raised edge of ground or a hill.

For translators

Meaning across languages The money bank, the river bank, and the store (blood bank) are often separate words in other languages; translate each sense on its own. A bank of screens or lights usually translates with a word for row.
Grammar trap Bank is countable: the bank, a bank. Money is in the bank, and you go to the bank; you have an account at or with a bank.
Cultural background In English-speaking countries a bank account is the normal way to be paid a wage and to pay bills, so the word appears in many everyday phrases: bank card, bank transfer, bank statement.
False friends In several languages a look-alike word means a bench or a seat, and in some a sofa; in English bank is never a seat.
Pronunciation trap The n is pronounced like the ng of sing, because it comes before k, so bank rhymes with thank and drank.
