Sure! Idioms are phrases that have figurative meanings that are different from their literal meanings. Here are a few idioms along with their explanations:

1. "Break a leg" - This idiom is often used to wish someone good luck, especially before a performance or event. It originated in the theater, where saying "good luck" was considered bad luck. Breaking a leg was seen as a way to counteract the curse.

2. "Piece of cake" - When something is described as a "piece of cake," it means that it is very easy or simple. The idiom comes from the idea that eating a piece of cake requires little effort or challenge.

3. "A dime a dozen" - This idiom means that something is very common or easy to find. It suggests that the item or idea being referred to is not of significant value, as dimes are considered to be of low worth.

4. "Bite the bullet" - When someone is advised to "bite the bullet," it means they are being encouraged to face a difficult or painful situation with courage and determination. The phrase originated from the practice of giving a soldier a bullet to bite on during surgery to help them endure the pain.

5. "Cat got your tongue" - This idiom is used to ask someone why they are still or silent, typically when they are hesitant or unable to speak. The origin of this phrase is uncertain, but one theory relates it to the idea that witches were believed to steal a person's voice or speech.

To access a comprehensive list of idioms, you can search online or refer to idiom dictionaries. There are many resources available that categorize idioms alphabetically, by theme, or based on specific languages or regions.
