In the Indo-European department of Leiden University, Alwin Kloekhorst has initiated a discussion on Hittite ammuk ‘me’. The central question is: where did the geminate come from? This has led me to reconsider the origin of the Indo-European personal pronouns against the background of my reconstruction of Indo-Uralic (2002: 221-225). For the historical data I may refer to Schmidt (1978)
