The book takes its cue from the topics of PhrasaLex, a workshop dedicated to phraseological approaches to learner’s lexicography which took place for the second time in July 2021 and is connected to the lexicographic project PhraseBase. Considering the great interest that studies on patterns of meaning have gained in lexicology and lexicography, we not only delve into the more phraseological approach, but broaden our horizon to include further approaches, both established and new, that have as their common thread the identification and analysis of patterns of meaning in their interaction with grammatical patterns. In this way, we present the commonalities of a complex, innovative and partly interdisciplinary strand of research that currently involves disciplines such as theoretical and applied linguistics, corpus linguistics and computational linguistics. The book provides insights into different theoretical approaches examining the interface between lexis, semantics and grammar, by dealing with methodological advances and issues regarding corpus linguistics explorations and the lexicographic process. A special focus is on the phraseological nature of language as well as on its implication for the design of (learner’s) dictionaries.
