Language and thought are intimately related: philosophers have long debated how a given language may condition the oral and written expression of thought. The language chosen to communicate scientific discoveries may facilitate or impede international access to such knowledge. Vector and message may become intertwined in ways not yet fully understood: comparing and contrasting dictionary definitions of key terms, such as the Humboldtian Weltansicht, may provide useful insights into this process. Semantic prosody, a linguistic phenomenon brought to light by corpus (...) linguistics through the analysis of ever vaster corpora, may have unsuspected and even unconscious impacts on the perception of a message. A case study of data from WebsTerre, a diachronic corpus of geological English, explores a twentieth-century Kuhnian paradigm shift in Earth Science, from continental drift to plate tectonics, to demonstrate how interactions between semantic prosody and translation have the potential to alter the history of science.
