'Time To Hit the Books!' 50 Common Idioms and What They Really Mean

Idioms—phrases that come to mean more than each word's "literal meaning" on their own—have been a part of spoken language for a long time. They may change as the years go by and often vary from country to country, language to language. An idiom's origin isn’t always well-known, but that doesn’t stop us from using them on a regular basis. Sometimes, a common idiom is so odd or old that no one can even pin down its meaning. For example, what does "the proof is in the pudding" really mean? Who came up with that anyway? 

Shakespeare—possibly.

After all, this beloved Bard is responsible for a number of other common sayings that have made their way into our everyday vernacular; such as "green-eyed monster," "in a pickle," "wear your heart on your sleeve," "cruel to be kind" and countless others. Shakespeare's phrases are still present in our lives and speech hundreds of years later.

Sometimes, idioms come from events of the day. Take "mad as a hatter," for example. There was a time when hat makers used mercury (recognized today as an extremely toxic substance) in their work. Unbeknownst to them, working with this chemical day after day took its toll; some hat makers (or hatters) really did "lose their marbles." Thus, an idiom (or two) was born.

Regardless of age, almost everyone uses these short phrases, often without realizing it. Perhaps our list of 50 English idioms will help you spice up your conversations.
