This article discusses methodological aspects of the role of the researcher in sociolinguistic
ethnographic studies with an interest in the linguistic repertoires of minorized speakers. Looking
at linguistic repertoires as knowledge that is to a large extent routinized, restructuration of those
repertoires is connected with communicative events that interrupt routines. In the context of
such events, the speaker mobilizes remote parts of his or her repertoire and reflects on linguistic
rules. Ethnographic research that involves intensive contact between the research subjects and
the researcher is likely to cause these kinds of events, which I call Ausbau events.
This paper argues that ethnographic linguistic research influences language use and
provokes metalinguistic reflection, both of which are seen as essential for language learning.
Referring to evidence from observations in a Ukrainian school in a northern Moldovan village,
the article discusses methodological aspects of this interference. Ausbau events are not regarded
as unnatural but rather as revealing of practices that would otherwise be inaccessible to
observation. On that account, including the role of the researcher into the analysis should be
seen as a chance to understand dynamic processes.
