A dataset of Polish multi-word expressions manually annotated with respect to their lexicality status. We show annotators' decisions with respect to two criteria: terminology (that is whether a given word combination can be classified as 'term', and 'paraphrase' (that is whether a given word combination can be can be easily paraphrased). In the last column, we present lexicographers' decision with respect to their lexicality status: "tak" - 'yes' means a given word combination is a multi-word lexical unit, "nie" - 'no' means it is not.
