This chapter reports on an indexicality study of standard and regional forms of the past participle of strong verbs in western Denmark (Jutland). The last decades have seen a strong standardisation process with respect to language use, and we test the hypothesis that this is driven by the social meanings associated with this morphological variation. We conducted an online matched guise experiment with controlled variation of the participle suffix using recordings with speakers from Eastern Jutland. 262 respondents evaluated the speakers on scales related to personality traits, social background and standardness. The results show that the most regional variant leads to a lower score in perceived standardness but, for younger respondents, a higher score in how “nice” the speaker seems.
