Cách sử dụng
The expression "peck at" means to eat food in small bites or nibbles over a period of time. It is often used when someone is not very hungry, or is not interested in the food they are eating. For example, if you have a small snack like popcorn and you only eat a little bit at a time, you could say "I'm just pecking at it." It can also be used more generally to describe any type of small, repeated action, such as a bird pecking at the ground with its beak.
