A lexicographer conducts a symphony, privately and perhaps silently. With every word, the dictionary-maker investigates and balances the semantics against the morphology, the syntax against the historical usages, the spellings and orthographic variants against the cognate languages. For every word, the balance of these elements must be exactly right, and is never exactly the same. One noun might be clarified by comparison with several prefixed versions of the same noun. Another might not. One preposition might have essentially the same usages as in one cognate language, but another might not. The lexicographer has to find her way through a grand and complex score, always ready to cue someone in or to insist on a slower crescendo of references, or a greater dynamic force given to one subset of semantic distinctions rather than another. Great conductors sweat the small stuff and let the big questions solve themselves. So also great lexicographers make sure every detail is checked and double-checked, every comma placed precisely where it disambiguates most helpfully, and every variation of usage elucidated, preferably with a solid contextual quotation from an appropriate text. Antonette diPaolo Healey is a great lexicographer, meticulous, focused, precise, always innovating so that she has the best tools at her disposal and the best modes and methods of publication, deeply learned, and deeply careful of sources, texts, and words. Those sources, texts, and words collect together into genres, and genre is among the many elements balanced by the lexicographer in the complex symphony that is lexicography. In the modern era we enjoy a proliferation of genres from which contextual quotations for dictionary entries can be identified, from tweets to blogs to prose poems to television shows to the Victorian or postmodern novel to rap poetry or spoken word poetry. Dictionaries generally try to balance their presentation of genres in individual entries, so as to demonstrate the generic similarity of usage, or indeed the different usage that a word can have in different genres. Genre, however, also has other implications. In many languages, and therefore dictionaries, genre functions as an index of culture, and one that changes over time.
