Abstract:The system BTT presents a basic model of the typology of Truncation, with emphasis on the role that Anchoring plays in it. In its assumptions about candidates, constraints and empirical matching, BTT is based on Alber&Arndt-Lappe (2012) and Alber&Arndt-Lappe (in prep.).
A single input is assumed, consisting of a five syllable string a b C d e, with C representing the main stressed syllable. Possible outputs are all contiguous substrings of a b C d e. Candidates are evaluated by three Anchor constraints, referring to the left and right edge, and the stressed syllable of the input. Anchor-Left and Anchor-Right are defined as constraints assigning violation marks for each syllable close to the left/right edge which is not realized in the truncated form. They are thus not Boolean, in nature, and therefore able to model gradient anchoring, encountered in truncation patterns of languages such as Russian or Czech (see Alber 2010, Alber&Arndt-Lappe 2012 for discussion). Candidates are evaluated by two size restrictor constraints, m.1s and m.2s, stating directly that outputs should be one or two syllables long.
The Factorial Typology of BTT consists of 10 languages which are first classified according to their extensional patterns and then analysed in terms of Property Theory (Alber&Prince 2015, ms.). Property analysis yields 5 Typological Properties, two of which refer to anchoring, three to the size of the truncated form. The particular interest of the property analysis of BTT lies in the fact that several of the uncovered Properties involve constraint classes derived from other Properties, in some cases in a recursive fashion.
