Deﬁnitions in the dictionary are everything.They aim to be clear and concise, so that a reader knowing little or nothing about a sport can understand the term in question. Cross references play their important part, with each word or phrase in an entry printed in bold having its own entry. The deﬁnitions of individual sports are necessarily concise, and like all entries occupy a single phrase or sentence. It would clearly be impracticable if not impossible to devote a single entry to the rules of a particular individual sport, let alone summarize its history. But equally the essentials of a game or sport, however familiar, must feature as prominently as the terms it uses.
