- Headword
A headword, head word, lemma, or sometimes catchword is the word under which a set of related
dictionary orencyclopaedia entries appears. The headword is used to locate the entry, and dictates its alphabetical position. Depending on the size and nature of the dictionary or encyclopedia, the entry may include alternative meanings of the word, itsetymology andpronunciation ,compound word s or phrases that contain the headword, and encyclopedic information about the concepts represented by the word.For example, the headword
bread may contain the following (simplified) definitions::Bread:"(noun)":* A common food made from the combination of
flour ,water andyeast :* Money "(slang)":"(verb)":* To coat in breadcrumbs:— to know which side your bread is buttered to know how to act in your own best interests.The
Academic Dictionary of Lithuanian contains around 500,000 headwords. TheOxford English Dictionary has around 300,000 headwords [http://www.oed.com/about/facts.html] , whileMerriam-Webster 's Third New International Dictionary has about 470,000 [http://www.merriam-webster.com/premium/mwunabridged/] . Both of these values are as claimed by the dictionary makers, and may not be using exactly the same definition of a headword. Also, the Oxford English Dictionary covers each word much more exhaustively than the Third New International.The term 'lemma' comes from the practice in Greco-Roman antiquity of using the word to refer to the headwords of marginal glosses in
scholia ; for this reason, theAncient Greek plural form is sometimes used, namely "lemmata" (Greek λῆμμα, pl. λήμματα).
