produces pairs like wine/whine, wet/whet, Wales/whales, wear/where, etc. homophones, in most cases eliminating , also transcribed , the voiceless labiovelar fricative. However, scatterings of older speakers who do not merge these pairs still exist nationwide, perhaps most strongly in the South. Vocabulary The process of coining new lexical items started as soon as English-speaking British-American colonists began borrowing names for unfamiliar flora, fauna, and topography from the Native American languages. Examples of such names are opossum, raccoon, squash, moose (from Algonquian), wigwam, and moccasin. American English speakers have integrated traditionally non-English terms and expressions into the mainstream cultural lexicon; for instance, en masse, from French; cookie, from Dutch; kindergarten from German, and rodeo from Spanish. Landscape features are often loanwords from French or Spanish, and the word corn, used in England to refer to wheat (or any cereal), came to denote the maize plant, the most important crop in the U.S. Most Mexican Spanish contributions came after the War of 1812, with the opening of the West, like ranch (now a common house style). Due to Mexican culinary influence, many Spanish words are incorporated in general use when talking about certain popular dishes: cilantro (instead of coriander), queso, tacos, quesadillas, enchiladas, tostadas, fajitas, burritos, and guacamole. These words usually lack an English equivalent and are found in popular restaurants. New forms of dwelling created new terms (lot, waterfront) and types of homes like log cabin, adobe in the 18th century; apartment, shanty in the 19th century; project, condominium, townhouse, mobile home in the 20th century; and parts thereof (driveway, breezeway, backyard). Industry and material innovations from the 19th century onwards provide distinctive new words, phrases, and idioms through railroading (see further at rail terminology) and transportation terminology, ranging from types of roads (dirt roads, freeways) to infrastructure (parking lot, overpass, rest area), to automotive terminology often now standard in English internationally. Already existing English words—such as store, shop, lumber—underwent shifts in meaning; others remained in the U.S. while changing in Britain. Science, urbanization, and democracy have been important factors in bringing about changes in the written and spoken language of the United States. From the world of business and finance came new terms (merger, downsize, bottom line), from sports and gambling terminology came, specific jargon aside, common everyday American idioms, including many idioms related to baseball. The names of some American inventions remained largely confined to North America (elevator [except
