Language is more than just grammar and vocabulary; it is full of expressions that make communication lively and natural.
One of the most powerful tools in English is idioms—phrases whose meanings are not always clear from the words themselves.
Idioms allow people to describe situations, emotions, and behaviors in colorful and memorable ways.
When it comes to describing something negative or unpleasant, idioms for bad are particularly useful.
They let you express criticism, disappointment, or failure in a creative way instead of using the same old word “bad.”
For example, instead of saying “He is very bad at singing,” you can say “He can’t carry a tune.” This makes your language more engaging and natural, just like native speakers.
In this article, you’ll discover a wide range of idioms for bad, organized into helpful groups.
You’ll also learn their meanings, examples, and similar expressions, along with tips on how to use them in speaking and writing.
