Idioms Lexicon

Okay kiddo, do you know what an idiom is? It's a group of words together that have a meaning that's different than the actual words themselves. For example, "break a leg" doesn't actually mean you should hurt yourself, instead it means good luck.

Now, a lexicon is kind of like a big dictionary where different words and phrases are listed with their meanings. So an idioms lexicon is like a special dictionary that lists all of the different groups of words that have a special meaning apart from the actual words themselves.

Each idiom usually has a specific cultural and historical background, which is why it's important to have a special dictionary just for them. It can be really fun to read and learn new idioms and what they mean, and can help you sound more like a native speaker of a language!
