In linguistics, particularly linguistic morphology, bracketing is a term of art that refers to how an utterance can be represented as a hierarchical tree of constituent parts. Analysis techniques based on bracketing are used at different levels of grammar, but are particularly associated with morphologically complex words. * "not eventful", where eventful in turn means "full of events" * "full of unevents", where unevent in turn means "something different from or opposite to an event"
