A. The Macquarie Dictionary is a record of Australian English – the English spoken by the Australian community. In some cases, the name of a product or service which started out as a trademark has, over time, been applied by that community more generally, to similar products or services. When it can be clearly established that this process has taken place, the term warrants an entry in the dictionary. Words such as this, which have senses which are derived from trademarks, have this information, where it can be ascertained, noted in the etymology.
It should be noted that the presence or absence of indication of this derivation should not be regarded in any way as affecting the legal status of any trademark.
