Derivatives are new words formed by the addition of a suffix, for example -al, -ly or -ness in English, to the headword.

Derivatives are treated as subordinate items to a main headword and introduced by the words ‘Hence’ or ‘So’. They are generally in a separate, labelled section at the end of an entry, followed by a single chronologically-arranged set of supporting quotations. For quick reference, a hyperlinked list of derivatives also appears in the side bar of the entry page.

ban, verb transitive. . . . Usually passive, of a person: to be placed under restrictions in terns of security legislation . . . Derivatives: Hence banned participial adjective, and absolutely, 'banned people'

Derivatives are often a different word class to the original word from which they are formed. For example, national, adjective is derived from the headword nation, noun. A part of speech is therefore provided for each derivative. Pronunciation is also given for those derivatives that do not fall within the general English vocabulary.
