The article analyzes the names for the eye disease stye, recorded in the dictionary of dialects of the Komi language (КСК 2012–2014), examining the semantics and formal structure of the names. The names under consideration are composite words and most of them contain the attributive component ’dog’ (pon, suka). The second part of the composite is either an independent word or a component not registered as an independent word in the modern language. At the base of the naming line for hordeolum in the Komi language is a metaphor based on the form ponč'up (lit. ’dog’s nipple’). Some names have acquired an internal form of ’nasty pimple, growth’ (ponč'uk). Despite the fact that the components of the considered ­composite words are of pre-Permian origin they came into use as names of the disease (with few exceptions) no earlier than the Komi period proper.
