On the So-Called "Covert Categories (exemplified by the Russian and English languages)
The paper treats the concept of a covert category in its narrow sense (as a category denoting grammatical meanings expressed by non-morphological means) and in its broad meaning (as semantic and syntactical characteristics affecting word collocation). The author adheres to the narrow treatment, as the broader one makes the target concept too vague and indistinct. Both approaches are illustrated by numerous examples.
