Briefly explain the principle of compositionality and one common misconception about it.

## Principle of Compositionality The **principle of compositionality** states that the meaning of a complex expression is determined by the meanings of its constituent parts and the way they are combined. In simpler terms: if you know what individual words mean and how they're put together grammatically, you can figure out what the whole sentence means. For example, understanding "black cat" requires knowing what "black" means, what "cat" means, and how adjective-noun combination works in English. ## Common Misconception A frequent misconception is that compositionality means meanings **simply add up** from the parts in a straightforward, mechanical way. In reality, compositionality allows for complex compositional rules and operations. For instance, "blue screen" can mean a literally blue-colored screen OR the technical term for a computer crash, depending on context and specialized composition rules. The principle doesn't require that meanings be transparent or predictable—just that they be systematically derived from components through some compositional process (which may be quite intricate).
