Моноколокабилни думи като компоненти на фраземи в българския и чешкия език

This is an attempt at a synchronic analysis of the so-called mono-collocable words, occurring as components of only one or few phrasemes, in Modern Bulgarian and Czech. Their form, meaning, function and collocability are considered in succession. The issues of category membership and place in the language system are given due attention. Some diachronic aspects are also tackled. In addition to the synchronic and diachronic analysis of the mono-collocable words, the similarities and dissimilarities observed in the Bulgarian and Czech material are thrown into relief.
