paksuudessa

Paksuudessa is the inessive form of the Finnish noun paksuus, which means thickness or density. It is used to express location inside something’s thickness or to describe a state related to density. In physical contexts, paksuudessa can refer to measurements such as the thickness of materials, for example seinän paksuudessa refers to within the wall’s thickness. In more figurative language, it can describe the density or richness of a texture, argument, or layer of information.

Etymology and form: The base noun paksuus stems from the adjective paksu, meaning thick. The suffix -uus creates the abstract noun, and the inessive suffix -ssa marks a location inside. Thus paksuudessa literally means “in the thickness.”

Grammar and usage: Paksuudessa is used with nouns that denote a physical layer or a conceptual boundary with measurable thickness, such as seinä, kerros or aine. It commonly appears with verbs of location or description, for example: Seinän paksuudessa on halkeama. Kerroksen paksuudessa esiintyy koostumusvaihtelua. Other cases of paksuus include paksuuden (genitive), paksuudesta (elative), and paksuuteen (illative).
