The article discusses the development of the Hebrew polysemous construction bɛsɛdɛr (the prefixed preposition bɛ ‘in’ + the noun sɛdɛr ‘order’). An analysis within the framework of Construction Grammar (Traugott & Trousdale, 2013) as well as tendencies of (inter)subjectification (Traugott, 2010, 2012) suggest that the construction developed through fusion and host-class expansion from an objective meaning of concrete and abstract order into an adverb, and later into a fully substantive lexical construction conveying subjective positive evaluation and to an intersubjectified discourse function expressing agreement and approval. The article further supports the proposal that both processes of grammatical and lexical constructionalization are evident in the constructionalization of beseder. Moreover, the analysis suggests that the different meanings which developed are interrelated, as they all derive from the original concept of order and organization, which at some point began to be desirable and appreciated, leading eventually to the development of discourse functions of approval and consent.
