Abstract
Logic developed a theory of names to which Polish logicians of the LvovWarsaw School eminently contributed. However, logicians do not delve into the structure of names of certain type, and treat them as inseparable lexical units. Yet in natural (e.g. Indo-European) languages there are words whose structure is decomposable into at least two elements. Such names are, among others, the subject of research of the linguistic area called word-formation.
