Dr Megan Tiddeman


I am a Research Fellow on the three-year Leverhulme-funded project, The Semantics of Word Borrowing in Late Medieval English, led by Professor Louise Sylvester.

I also worked as Research Fellow on Professor Sylvester’s previous project - Technical Language and Semantic Shift in Middle English - here at the University of Westminster from March 2019 to September 2020. Prior to this, I spent two years as a Postdoctoral Research Assistant working with the Anglo-Norman Dictionary (AND) team at Aberystwyth University.

I graduated in French and Italian from the University of St Andrews and gained my PhD in Historical Linguistics from Aberystwyth University.  I was supervised by the late Professor David Trotter and funded by an Aberystwyth Postgraduate Research Scholarship. My thesis examined language contact in late medieval trade documents between Italian dialects and both Anglo-Norman and Middle English.


I am interested in Middle English's lexical and semantic development and interaction with Anglo-Norman, as well as medieval Anglo-Italian language contact, especially in non-literary sources.

My edition of a fifteenth-century Anglo-Tuscan account book (Archivio Salviati Serie I: 339) for the British Academy's Records of Social and Economic History series was published in November 2022 by OUP:
