This paper investigates virtues of creative abductive concept formation and its application to conceptual engineering. It is shown that virtues of the abductive framework are in line with conditions of adequacy put forward in conceptual engineering. It is argued that a widened interpretation of the Carnapian conditions, i.e. the similarity, the exactness, the fruitfulness, and the simplicity requirement, is still guiding revisionary projects. It is then outlined that the latter three of the Carnapian conditions have a direct match in creative abductive concept formation, but that also the requirement of similarity has relevant bearing on the issue.
