Peckish is an adjective which can mean to be bothered/annoyed or to be famished. The hungry meaning is most popular in British English. The annoyed definition is quite less common, and almost exclusively found within the United States.
The adjective comes from the verb peck, which can mean to strike the ground with a beak or to pick at food and eat slowly. A third definition is to kiss quickly.
The noun form of this adjective is peckishness, but it is not recognized by most dictionaries as is best avoided in formal writing. (Though we found it in several leading newspapers.)
