- Functional shift
In
linguistics , functional shift occurs when an existing word takes on a new syntactic function. For example, the word "like", formerly only used as apreposition in comparisons (as in "eats like a pig"), is now also used in the same way as thesubordinating conjunction "as" in manydialect s of English (as in "sounds like he means it"). The boundary between functional shift and conversion (the derivation of a new word from an existing word of identical form) is not well-defined.Shakespeare uses functional shift, for example using a noun to serve as a verb. Researchers found that this technique allows the brain to understand what a word means before it understands the function of the word within a sentence.
