Procesele dinamice în evoluţia semantică a unităţilor polilexicale stabile din limbă pot duce la dezvoltarea polisemiei; la derivarea frazeologică şi anume: la crearea cuvintelor noi, formarea noilor sensuri la cuvintele componente ale unităţilor polilexicale stabile, căpătarea unui nou sens nu doar la un cuvânt aparte, dar la o îmbinare de cuvinte; la defrazeologizare.

The dynamic processes in the stable poly-lexical units semantic evolution in a language, can lead to the polysemy development, phraseological derivation and namely: the creation of new words, the formation of new meanings in the elements of stable poly-lexical units, the acquisition of a new meaning not for a single word only, but for a word – combination as well; and to the dephraseologisation.
