We present a precis-of an approach to relevance as it pertains to weak conditionMs and defeasible reasoning. The notion of relevance is taken as a relation between a property (such as, being green) and a conditional (such as, birds fly). A series of principles characterising a minimal, parsimonious notion of relevance is developed. Lastly, an explicit definition that agrees with the postulates is given.
