Kopsudest

Kopsudest is an Estonian word meaning "from the lungs." It is the elative case form of the plural noun kopsud (lungs). In Estonian, the elative suffix -est is used to express origin or source, so kopsudest translates to "from the lungs."

The form is primarily found in medical, anatomical, or clinical writing, as well as in descriptive passages about respiration or pulmonary tissue. It is not typically used in everyday conversation outside of such contexts. For example, a sentence might read: "Proov võeti kopsudest," meaning a sample was taken from the lungs.

Etymology and morphology: kopsudest is built from kopsud (the plural of lung) plus the elative suffix -est. The singular counterpart is kopsust, meaning “from the lung.” This illustrated form shows how Estonian builds location- or origin-related phrases through case endings attached to noun stems.
