Examples

Morphology

erythrocyte + sedimentation + rate

The phrase is fully compositional: erythrocyte (red blood cell) + sedimentation (settling) + rate (speed/measure) yields the rate at which erythrocytes settle. Although the term is technical and contains a low-frequency noun, the overall meaning is directly derivable from the constituent meanings and follows a transparent, cross-linguistic noun-modifier composition.

Etymology

Erythrocyte sedimentation rate comes from a simple lab picture: erythrocyte means 'red blood cell', sedimentation is the settling, and rate is how fast they fall in a test tube. Doctors measure how fast the red cells fall, and a faster fall often shows 'inflammation' or illness, so the name tells what the test measures.
