syvyydellä

Syvyydellä is the adessive singular form of the Finnish noun syvyys (depth). It expresses location at a certain depth within a medium, most often water, but also in soils, ice or other fluids where depth can be measured. In Finnish grammar it is an adessive form, used to indicate that something is located on or at the specified depth within the medium. The term is common in scientific, nautical, and diving language, where depth is a key parameter. It can be used with measurements or depth descriptors to specify where an object or phenomenon is found or observed.

Usage and context: The word appears in fields such as oceanography and hydrology, where depth profiles and layers are described; geology and archaeology for subsurface contexts; and diving or fishing reporting for depth-based observations. It can also occur in metaphorical expressions to indicate a level of intensity or thoroughness, though in everyday Finnish more common senses for thoroughness are expressed with words like syvällisesti or perusteellisesti.

Etymology and morphology: syvyydellä is formed from the root syvyys (depth) with the adessive suffix -llä. The form follows standard Finnish case grammar and can be inflected for number and possessive as needed (for example syvyydellä, syvyydelläsi, syvyydellämme).
