The ‘Word Links’ panels at the end of certain entries supply words which are not actual synonyms but which have a different kind of relation to the headword. For example, at milk, the adjective relating to
milk is given (lactic); at town, the related adjectives urban, municipal, and the rarer oppidan. Examples of other types of relation include collective nouns (e.g. school at dolphin, or charm at finch); the male, female, or young of an animal (e.g. levret at hare, or tom, queen, and kitten at cat); phobias (e.g. arachnophobia at spider); the study of a particular subject (e.g. bryology at moss); and a geometric figure with a given number of sides (e.g. pentagon at five).
Some word links are prefixes or suffixes related to the headword, such as photo- at light, cerebro- at brain, and -metry at measurement: knowledge of prefixes and suffixes helps the user to understand many new or unfamiliar words, such as photometry and cerebrospinal.
