flaky

Think of a pastry: when it's flaky, it breaks into light, thin layers. But this word is not just about food. It can also describe a person who is unreliable or hard to depend on. A flaky friend might say they will help you move, then not show up on moving day. The idea comes from something that comes off in small pieces, like skin or old paint.

The word "flaky" has two main uses. First, it describes something that easily separates into thin layers or small pieces. You can use it for food, especially pastries like croissants or pie crusts, when they have a light texture that breaks into layers. It can also describe things like dry skin or old paint when small bits come off.

Second, "flaky" is often used in an informal way to describe a person who is unreliable, inconsistent, or likely to cancel plans at the last minute. A flaky coworker might promise to help with a project but then become unavailable when you need them. In this sense, the word suggests that the person cannot be counted on.

The word comes from flake, meaning a small thin piece. That connection helps the two meanings make sense: something can literally come apart in flakes, or a person can seem unreliable and not steady. In everyday English, the second meaning is very common, especially in casual speech.
