Language cultivation is an approach to language planning which was originally designed in the early 20th Century by linguists of the Prague Circle. In order to support social modernisation within a nation-state, they advocated proactive development of the standard language, with the aim of preparing it to fulfil the widest possible array of functions. This approach to language planning was very quickly taken up by scholars in Slovenia, where it blended together with a tradition of aggressive purism. In my talk, I examine the legacy of this tradition in current Slovenian society against the background of a critical approach to language policy. I briefly present more traditional means of prescription before analysing a recent interactive quiz about grammar and orthography. I conclude by presenting the potential of this tradition to support social transformation towards a more inclusive and democratic multilingual society.
