<P> A lexical conception of polysemy was developed by B.T.S. Atkins, in the form of lexical implication rules . These are rules that describe how words, in one lexical context, can then be used, in a different form, in a related context . A crude example of such a rule is the pastoral idea of "verbizing one's nouns": that certain nouns, used in certain contexts, can be converted into a verb, conveying a related meaning . </P> <P> Another clarification of polysemy is the idea of predicate transfer--the reassignment of a property to an object that would not otherwise inherently have that property . Thus, the expression "I am parked out back" conveys the meaning of "parked" from "car" to the property of "I possess a car". This avoids incorrect polysemous interpretations of "parked": that "people can be parked", or that "I am pretending to be a car", or that "I am something that can be parked". This is supported by the morphology: "We are parked out back" does not mean that there are multiple cars; rather, that there are multiple passengers (having the property of being in possession of a car). </P>
