An indicator of high regularity of a phraseological system is its affinity for discreteness and orderliness, for building sets, series and paradigms, and for repeated use of the same lexical elements. The degree of regularity of phraseological system is thus conditioned by the activity of structural-combinatorial principle. In other words, the more regular the phraseological system of a language is, the more uniform is its internal structure and the more often phraseologization picks up structural patterns already known and previously used. (Dobrovol’skij 1992: 297-8)
