This is the second volume of papers on sign-based linguistics to emerge from Columbia School linguistics conferences. One set of articles offers semantic analyses of grammatical features of specific languages: English full-verb inversion; Serbo-Croatian deictic pronouns; English auxiliary do; Italian pronouns egli and lui; the Celtic-influenced use of on (e.g., ‘he played a trick on me’); a monosemic analysis of the English verb break. A second set deals with general theoretical issues: a solution to the problem that noun class markers (e.g. Swahili) pose for sign-based linguistics; the appropriateness of statistical tests of significance in text-based analysis; the word or the morpheme as the locus of paradigmatic inflectional change; the radical consequences of Saussure’s anti-nomenclaturism for syntactic analysis; the future of ‘minimalist linguistics’ in a maximalist world. A third set explains phonotactic patterning in terms of ease of articulation: aspirated and unaspirated stop consonants in Urdu; initial consonant clusters in more than two dozen languages. An introduction highlights the theoretical and analytical points of each article and their relation to the Columbia School framework.
