This study investigates interpretations of the Japanese initial mora-based minimizer "X.Y..."-no "X"-no ji-mo 'lit. even the letter "X" of "X.Y...".' Although initial mora-based minimizers have a literal interpretation of ji 'letter', they have a non-literal interpretation as well. The non-literal interpretation has several distinctive features that are not present in ordinary minimizers. First, it is highly productive in that various expressions can appear in the form "X.Y..."-no "X"-no ji. Second, non-literal minimizers typically co-occur with predicates that relate to knowledge, information, concepts, thought, and habituality, as seen in the corpus data (Balanced Corpus of Contemporary Written Japanese [BCCWJ]).I argue that in the non-literal use, X refers to the minimum on the scale of the main predicate concerning "X.Y...". I suggest that the non-literal use was developed as a result of the conventionalization of the pragmatic inference derived from the literal reading, and that the co-occurrence with predicates related to knowledge, information, knowledge, concepts, thought, or habituality is due to the interpretation of "X.Y...", which were originally interpreted as letters as an abstract concept.The theoretical implication of this study is that, in addition to a non-compositional (lexically specified) minimizer whose scale is lexically fixed (e.g., give a damn, lift a finger), there also exists a compositional (lexically unspecified) minimizer in natural language, whose scale is specified via the predicate with which the minimizer co-occurs. The last section of this paper briefly discusses similar/related phenomena in Bosnian/Croatian/Serbian, Korean, and English from a cross-linguistic perspective.
