At the phonological level, Tashlhiyt Berber features remarkably long strings of consonants with no intervening vowels [5, 22]. Past research on the topic has investigated the structure of syllabic constituents, suggesting that in spite of its acknowledged complexity, the language favours syllable structure with simple onsets [4, 5, 23]. In this preliminary work, we upturn the traditional idea of evaluating syllable formedness, and provide a feature-based analysis of vowelless verbal roots. Methodologically, the study draws on bottom-up approaches to phonotactics [16, 17] which lead to the formulation of new preferences on the basis of a qualitative and quantitative description of segments forming clusters. The identification of such preferences has the potential of revealing phonological properties which motivate the unique patterning of consonant sequences in the language.
