This paper argues for a distinction between “conduct politeness” and “etiquette politeness”, where the former refers to the propriety of what people do and the latter to the decorum of how people do things. In everyday discourse, the distinction is often fuzzy, but as a second order distinction the terminology provides a useful analytical tool. In the history of politeness in English, a bifurcation into the two types of politeness can be observed in the eighteenth century, and today the distinction provides additional conceptual clarity of the changing theoretical focus during the three waves of politeness theory. After a review of the historical link between morals and manners, a brief case study focuses on their separation in the eighteenth century. A final discussion applies the distinction to the paradox that politeness is often seen as a positive thing that, unfortunately, is on the decline and as a negative thing because it is insincere, superficial and hypocritical.
