piikkiä

Piikkiä is the partitive singular form of the Finnish noun piikki, which generally refers to a sharp point or projection. In everyday language piikkiä can denote a physical spike or thorn, such as the pointed end of a tool, a plant spine, or a projecting tooth on a mechanism. The term is also used metaphorically to describe a sudden increase in numbers or values, for example in data, prices, or measurements, where a “piikki” or “piikkiä” denotes a spike or peak.

The noun piikki has several related senses. It can describe an anatomical or botanical sharp projection (thorn, spine, or needle-like structure), a mechanical tooth or projection on a gear, comb, or fastening element, and in statistical or economic contexts a rapid rise or spike. The language uses the same root to cover both concrete objects and figurative intensifications.

Grammatically, piikkiä is the partitive singular form used when the object is indefinite or part of a larger context, such as in non-countable or fragmentary references. Other forms include piikki (nominative singular), piikin (genitive), piikit (nominative plural), and piikkejä (partitive plural). The word is common in technical writing, botany, engineering, and everyday speech.
