At the center of this paper is the question whether presuppositions are more likely to be gained or lost in the process of language change. We offer a new experimental method that aims at ascertaining the re-learning speed of potentially presuppositional items based on nonce words and which integrates certain factors of change such as social prestige in an artificial but clearly contextualized set-up. The meaning targeted is of a quantifier meaning ‘both’ with speakers of German and the initial results point to higher ease of losing rather than incorporating the presupposition, but with an interesting resilience after a critical questioning of presuppositional status.
