Segmentability and Transparency in English Latinate Prefixation

English suffixes have been the object of sustained inquiry across most phonological schools and paradigms, e.g. Chomsky‒Halle’s SPE, Lexical Phonology, Distributed Phonology (see, e.g. Booij 2005; Scheer 2011; Chornogor 2007; Rakić 2007; Carr 1993, for overviews and a sample discussion). In the current article I assume a ‘panchronic’ view (cf. Pociechina 2009) of selected issues implicated in English Latinate prefixation ({con-} and {ex-}) and I propose interpreting the apparent contrarieties in their productivity and phonological behavior as a canonical case of segmentability (cf. Bynon [1977] 1996; Nagano 2007).
