Polish is a language with true lexical geminates that form minimal pairs with their singleton counterparts. What is more, Polish, unlike many other geminating languages, allows both single-articulated and rearticulated geminate realisations. It seems to be a unique feature, since geminates are traditionally considered to be long counterparts of corresponding singletons and rearticulation is not discussed in any comprehensive accounts of gemination in the world’s languages. In this talk, I will demonstrate acoustic-phonetic characteristics of Polish geminates in order to trigger a discussion on how rearticulation may be incorporated into phonetic and phonological theories of gemination.
