American English has always shown a marked tendency to use words in different parts of speech and nouns are often used as verbs. Examples of nouns that are now also verbs are "interview, advocate, vacuum, lobby, pressure, rear-end, transition, feature, profile, hashtag, head, divorce, loan, estimate, X-ray, spearhead, skyrocket, showcase, bad-mouth, vacation, major," and many others. Compounds coined in the U.S. are for instance "foothill, landslide" (in all senses), ", teenager," brainstorm, , hitchhike, smalltime, and a huge number of others. Other compound words have been founded based on industrialization and the wave of the automobile: five-passenger car, four-door sedan, two-door sedan, and station-wagon (called an estate car in England). Some are euphemistic "(human resources, affirmative action, correctional facility)." Many compound nouns have the verb-and-preposition combination: "stopover, lineup, tryout, spin-off, shootout, holdup, hideout, comeback, makeover," and many more. Some prepositional and phrasal verbs are in fact of American origin ("win out, hold up, back up/off/down/out, face up to" and many others).
