Abstract
A particle as the most active functional morphological class in the Ukrainian dialectal speech needs attention in the investigation of the Ukrainian different origin dialects spoken in South Bessarabia. The article deals with the functioning peculiarities of different morphological particle types (emphasising, demonstrative, affirmative, intensifying, negative, form-building, derivative etc.). The author highlights the wide ambivalent possibilities of particles towards other grammatical classes, especially interjections.
