An idiom is an expression or saying that means something other than its literal translation, and the British English language has hundreds, possibly thousands to get your head around. Learning British idioms will not only improve your creative writing skills, but also increase your everyday conversational skills.
1. Never wash your dirty linen in public
This idiom doesn’t literally refer to y-fronts, but instead to your personal life. British people have a reputation for being quite prudish and secretive when it comes to their personal relationships, and so in past times it was considered uncouth to talk about or expose one’s personal life outside the confines of your home. An example of washing your dirty linen in public would be arguing about an extra-marital affair with your husband in front of the neighbors.
2. Treading on thin ice
To tread on thin ice is to swim In deep water, which is another idiom, by the way. Both mean to put yourself in unnecessary danger, to walk a pathway likely to present you with problems or trouble in the near future.
3. To tiptoe on broken glass
Do you know someone who is extremely sensitive, someone who is likely to become angry at the slightest misplaced comment? Well, when you are around this person you must ‘tiptoe on broken glass’ to make sure you don’t say the wrong thing.
4. A waste of space
In the opinion of the accuser, a person who is a “waste of space” is taking up too much room on the earth. They are a waste of time and energy, and generally not worth bothering about. The implication here is that the space the person takes up would be better used for something else.
5. Getting on his/her high horse
A person saddling up in this way is considered to be taking a moral stand in an authoritative, arrogant and often aggressive manner. This idiom is usually reserved for someone who regularly acts this way; “Oh my, here we go. He’s getting on his high horse again.”
6. Making a mountain out of a molehill
This idiom is used for a person who makes something out of nothing. For example, a person who unnecessarily makes a small problem into a big one is making a mountain out of a molehill.
