This article investigates semantic prosody in a diachronic perspective. Although prosodies have been shown to change over time, there is no consensus regarding the source of such changes. The present study explores this further through a corpus study of the development of the lemmas , and from the late 15th century to the late 20th century, drawing on material from Early English Books Online, the Corpus of Late Modern English Texts and the British National Corpus. The results of the study show that prosodic changes coincide with the emergence of new senses and indicate that these processes are related to and possibly caused by semantic transfer induced by persistent prosodies over time.
