**About myself** I am a PhD student in the University of Dusseldorf writing my thesis about valence-increasing devices supervized by Prof. Laura Kallmeyer and Prof. Robert Van Valin. My main research interests are syntax, typology, semantics, and linguistic theories, namely Role and Reference grammar. For contacting please use *generalo (at) hhu (dot) de* or personal messaging in Slack. **Abstract** This paper suggests a method of formal modeling of constructions with morphological causatives based on transitive verbs in three languages: Nivkh (Isolate, Sakhalin island), Bashkir (Turkic, Ural region), Halkomelem (Salish, Southwestern British Columbia). It aims to present an analysis robust enough to apply to different languages, formal enough to be used for computational tasks (such as parsing and sentence generation), easily extendable and in line with modern linguistic theory. We are working within Role and Reference Grammar and use tree and frame representations with typed features. This approach allows us to create complex data structures and ensure correct linking. We show that constructions with morphological causatives based on transitive verbs can be syntactically and semantically decomposed in a similar way independently on the language. Features determining each particular construction can be introduced for any dimension: syntax, semantics, morphology, and pragmatics. Although only two of them seem to be critically relevant for the universal concept of a causative construction, other features are shared across languages. Our method is easily extendable over other structurally varied languages since constructions with more modifications automatically inherit features from more general constructions.
