Understanding prescription in language. A corpus-based approach

We define prescription as any intervention in the way another person speaks. Long excluded from linguistics as unscientific, prescription is in fact a natural part of linguistic behavior. We seek to understand the logic and method of prescriptivism through the study of usage manuals: their authors, sources and audience; their social context; the categories of “errors” targeted; the justification for correction; the phrasing of prescription; the relationship between demonstrated usage and the usage prescribed; the effect of the prescription. Our corpus is a collection of about 30 usage manuals in the French tradition. Eventually we hope to create a database permitting easy comparison of these features
