A contraction is a shortened version of the written and spoken forms of a word, syllable, or word group, created by omission of internal letters (actually, sounds). In traditional grammar, contraction can denote the formation of a new word from one word or a group of words, for example, by elision. This often occurs in rendering a common sequence of words or, as in French, in maintaining a flowing sound.In linguistic analysis, contractions should not be confused with abbreviations nor acronyms (including initialisms), with which they share some semantic and phonetic functions, though all three are connoted by the term "abbreviation" in loose parlance. Contraction is also distinguished from clipping, where beginnings and endings are omitted.
