Apart from sayings and proverbs, the English language is full of interesting expressions we call idioms, or idiomatic expressions. As we know, these idioms can be quite hard to get, since many of them can´t be interpreted literally. Take for instance: He was pulling my leg. Do you mean that somebody had actually grabbed your leg and started pulling it, as if to rip it off your body? Of course not. And How about: I have to hit the road. Hit the road?, with a hammer?
The thing is, English is such a colourful and varied language that, if we don´t pull up our socks and learn some of these idiomatic expressions, we can find ourselves between a rock and a hard place.
