Examples
-

Morphology
The compound combines 'hair' and 'cell' transparently, so a learner who knows the words will likely infer it denotes a type of cell related to hair-like structures. However, the specific technical sense — an inner-ear sensory receptor that detects sound vibrations — is specialized and not fully predictable from the constituents, so the precise function would typically require prior exposure.
Etymology
Hair cell is named for the tiny hair-like parts on the cell surface that move when sound reaches the inner ear. That's why the name refers to a sensory cell that 'detects sound'.
