skorupki

Skorupki is a Polish noun meaning shells or outer coverings, especially eggshells. The term refers to the hard outer layer of eggs (skorupki jaj), as well as shells of mollusks, nutshells, or fruit crusts. The word derives from skorupa, meaning shell or crust, with the diminutive skorupka; skorupki is the plural form.

In everyday language skorupki is used to denote physical shells. Common phrases include skorupki jaj, skorupki orzecha, and skorupki ślimaków. Beyond its literal sense, skorupki may be used in crafts and gardening. Crushed skorupki jaj are often used as a calcium-rich soil amendment or compost additive, although the practice is more common in rural contexts. In crafts, skorupki may be used for mosaic work or decorative effects, especially when shells are cleaned and prepared for such use.

The word can occur in surnames or toponyms, reflecting its origins as a descriptor for someone associated with shells, crusts, or a place name. In Polish, skorupki is the plural nominative for a feminine noun and agrees with the noun it modifies.
