17 DUCK Idioms and Expressions

Meaning: to achieve your first success or score for the first time, particularly after several unsuccessful attempts. It is mainly British and informal, especially common in sport.

The expression originally comes from cricket, where a score of zero is called a duck.

Usage: informal British English

6. Duck down

Meaning: to lower your head or body quickly, usually to avoid being seen or hit

Unlike many expressions in this lesson, duck down is usually literal rather than idiomatic.

8. Duck out of something

Meaning: to avoid a duty, activity or responsibility, often by making an excuse

Meaning: a humorous expression used when the weather is very wet or rainy. It is common in British English.

The expression is mildly humorous because ducks are perfectly happy in wet weather, even when humans are not.

11. Get, have or put your ducks in a row

Meaning: to become well organised and make all the necessary preparations

• We need to have all our ducks in a row before launching the product.

This is a useful expression for work, business, exams and everyday planning.

Meaning: a person or thing that is easy to attack, criticise, defeat or take advantage of
