Abstract: It is argued that the collections of combinations of content words in the modern general-purpose electronic dictionaries are to be broadened as much as possible. I. Mel’čuk classifies word combinations into complete phrasemes, semi-phrasemes (combinations with lexical functions), and free combinations. Our suggestion is obvious for complete phrasemes and semi-phrasemes; however, combinations with nonstandard lexical functions, poorly studied and difficult to detect, as well as terminological combinations, are also to be acquired since they are highly language-specific. In addition, we propose heuristic rules for including free word combinations into dictionaries. According to our ex-perience with the CrossLexica word combination database, these rules do not cause any significant growth of the mean number of combinations per content wordžbecause of the mutual semantic selectivity of the words to be combined.
