In Kovecses explanation of entaillments there are additional possibilities for extending metaphor. He describes concepts as having aspects (I might prefer to call them dimensions or attributes) and each aspect as having elements (subattributes). These elements comprise the detailed knowledge one has of the source domain. Not all of this is transferred automatically to the target domain. He talks about the invariance principal as explaining how some of these elements are not transferred. However there are examples (e.g., Shakespear talking about death as "to sleep/perchance to dream?") where elements not normally transferred can be suggested and they fit or pose an interesting question (do we dream when we are dead? what if we did, what would the dream be?).

The questioning process merges into the process of extending metaphor. In mediation the idea is to expand and deepen meanings as already partially understood by clients. As meaning is enlarged, ramifications and dimensions added, new associations and connections spun out, weaving a web of correspondences, we assume that something of great importance in mediation may occur -- the expansion of possible client options and alternatives of thought and action.

Kovecses (2002) summarizes half a dozen different ways that metaphors already operating might be broadened, animated, altered, etc.: elaboration, extension, questioning, combining, personification, megametaphors and micrometaphors.
