A headword, head word, lemma, or sometimes catchword is the word under which a set of related dictionary or encyclopaedia entries appear. 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, its etymology and pronunciation, compound words 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 and yeast : * 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. The ''Oxford English Dictionary'' (OED) has around 273,000 headwords,〔http://public.oed.com/how-to-use-the-oed/glossary/〕 while ''Merriam-Webster's Third New International Dictionary'' has about 470,000.〔http://www.merriam-webster.com/premium/mwunabridged/〕 The ''Deutsches Wörterbuch'' (DWB), the largest lexicon of the German language, has around 330,000 headwords.〔(The Deutsches Wörterbuch ) at the BBAW, retrieved 22-June-2012.〕 These values are cited by the dictionary makers, and may not use exactly the same definition of a headword. In addition, headwords may not accurately reflect a dictionary's size. The ''OED'' and the ''DWB'', for instance, include exhaustive historical reviews and exact citations from source documents not usually found in standard dictionaries. 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, the Ancient Greek plural form is sometimes used, namely ''lemmata'' (Greek λῆμμα, pl. λήμματα). ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「headword」の詳細全文を読む スポンサード リンク
