<P> In linguistics, a word is the smallest element that can be uttered in isolation with objective or practical meaning . </P> <P> This contrasts deeply with a morpheme, which is the smallest unit of meaning but will not necessarily stand on its own . A word may consist of a single morpheme (for example: oh!, rock, red, quick, run, expect), or several (rocks, redness, quickly, running, unexpected), whereas a morpheme may not be able to stand on its own as a word (in the words just mentioned, these are - s, - ness, - ly, - ing, un -, - ed). A complex word will typically include a root and one or more affixes (rock - s, red - ness, quick - ly, run - ning, un-expect - ed), or more than one root in a compound (black - board, sand - box). Words can be put together to build larger elements of language, such as phrases (a red rock, put up with), clauses (I threw a rock), and sentences (He threw a rock too, but he missed). </P>
