cidate several interdisciplinary imaginative practices. It presents examples of verbal invention in the publications and rhetorical practices of three geographers, Francis Galton, John Frederick Heyes, and Halford Mackinder, which demonstrate individual words, especially neologisms and portmanteau words, can reflect concepts of space and disciplinary spaces. The paper traces perceptions of the relations between word-making and world-making via examples of re-scaling,including magnification and shrinkage of words, as well as the moving, subtraction, and addition of syllables or letters in certain words, including geography, philosophy, and geosophy. In drawing on the wordplay of these figures, it argues that portmanteau words evidence parallels between late 19th-century and early 20th-century chemical and geographical practices that have important implications for 20th-century geographies and languages of knowledge-making.geosophy, history and philosophy of geography, interdisciplinarity, language, portmanteau The power by which we thus picture to ourselves effects beyond the range of the senses is what philosophers call the Imagination … Without imagination we might have critical power, but not creative power in science. (Tyndall, 1872, p. 34) It is in this nexus of representation, words, and space (the words representing the space of representation, and in turn representing themselves in time) that the destiny of peoples is silently formed.

| INTRODUCTIONAlthough imaginative practices are essentials in our historical toolkits, their processes, terminology, and expression are ill-defined. Their embodied cognitive practices, and shifting temporal and spatial definitions and implementations, remain uncritically harnessed. This paper therefore elucidates the spatio-temporalities of imaginative practices by mapping several examples of portmanteau words and wordplay conceived by geographers (
