Pomak is a non-standardised, endangered language variety of the East South Slavic dialect continuum. This article presents an online resource of 165 Pomak verbal multiword expressions collected via fieldwork. The resource has been developed with IDION, which is a web-based environment for the documentation of a wide range of multiword properties. The following information is encoded in this resource: lemma form of the expression, variants (if attested), definition in Pomak and translation in other languages, gloss, usage examples for 60 verb multiword expressions, morphosyntactic analysis in the Universal Dependencies framework as well as certain lexical relations among multiword expressions and verb alternations (if attested). Observations on the collected material that are not encoded in the Pomak edition of IDION but are presented in the article concern the types of verbal multiword expressions found in the data (light verb constructions, idioms) and the occurrence of very similar expressions in Modern Greek. The contents of Pomak-IDION are openly available; they belong to a set of resources of Pomak (corpus, morphological and syntactic models, embeddings, lexica) that have been developed as a case study of the Philotis project, which provides technological support for the documentation of living languages.
