A comprehensive description of the combination of the finite auxiliary verbs wērden ‘become’/wēsen ‘be’ and a present participle in Middle Low German is still a strong desideratum. This study presents a corpus-based analysis of the aforementioned phenomenon with a special focus on its grammatical structure and its different meanings. In particular, it focuses on a wide range of temporal and aspectual meanings, depending on the auxiliary verb, its tense and mood. Moreover, the relationship between the semantics of the main verb and the meaning of the whole construction is investigated. Finally, the competition with alternative verbal complex constructions expressing the same meaning is also explored. The analysis is carried out on the basis of Middle Low German texts from different times, language areas, and genres.
