Sirpaleisuus

Sirpaleisuus is a Finnish noun denoting the state or quality of being shard-like or fragmented. The word is formed from sirpale ("shard, fragment") plus the abstracting suffix -isuus, which marks a property. In everyday language sirpaleisuus can describe objects that are broken into pieces or have jagged, uneven edges, such as pottery fragments, glass, or rock surfaces. In technical contexts, the term is used to describe fragmentation patterns or texture that resembles shards, for example in geology, archaeology, or materials science.

In geology, sirpaleisuus may refer to a rock's surface pitting and fracture pattern that yields a splintered appearance. In archaeology, it can characterize the fragmentation of a ceramic assemblage or the edges of broken pottery. In art and literature, the concept can be used metaphorically to express fragmentation of form, memory, or social structure.

There is no universally defined quantitative measure for sirpaleisuus; assessment is typically qualitative, focusing on the degree of fragmentation, approximate shard size distribution, and edge irregularity. The term remains relatively descriptive and is more common in descriptive writing and field notes than in formal technical vocabulary. Related terms include sirpale, sirpaleinen (shard-like), and synonyms referring to jaggedness and fragmentation.
