Abstract
Conceptual metaphors, as theorized by George Lakoff, are essential to scientific and biomedical thought. They express themselves in speech through metaphorical expressions. Understanding conceptual metaphors is critical for translators. Several years ago we proposed the concept of conceptualization index, which is the linguistic element by which metaphor operates. This article begins with a description of the experiential framework used for a number of studies realized in biomedicine and life sciences. Then, the predicative, quasi-predictive, and non-predictive conceptualization indices are distinguished. Finally, the general principles deduced from the set of data are presented.
