From the name to the popular image of the plant: the Polish names for the black elder (Sambucus nigra).

The names of plants convey information on their appearance (shape, structure, colour), taste or smell, their uses (practical, ceremonial, magical and medicinal) as well as the beliefs and convictions associated with them. Assuming that the particular features of plants, entrenched in their names, must have been important to language users for some reason, the analysis of plant names can help reconstruct traditional knowledge about plants. The author analyses the standard and dialectal names for the black elder (Sambucus nigra) in Polish, juxtaposing the plant's features revealed in its names (linguistic data) with the cultural accounts associated with the plant ("with-linguistic" data). This allows for the reconstruction of the following features of the plant: (a) the appearance of the shrub, (b) the properties of its fruit, (c) the smell of the plant, (d) the place where it grows, (e) the time of harvesting, (f) its use in folk medicine and (g) the association of the plant with impure powers and diseases. The conducted analyses show that reaching for hard "linguistic evidence" (standard and folk names) makes it possible to compile hierarchies of the characteristics of the plants described. Situating these names against the background of "with-linguistic" data leads to the conclusion that folk nomenclature and folk knowledge enrich and complement each other. The vast number of names for the black elder with different onomasiological bases, presenting different points of view, also demonstrate the relationship between the degree of lexical differentiation and the cultural meaning of the plant. The ethnolinguistic analysis of the names for the black elder (Sambucus nigra), similarly to ethnobotanical studies of folk plant names, provides insights into past and contemporary uses of the plant. Thus, it can provide a starting point for further ethnobotanical research.
