Etymology
The word 'saccule' is a direct borrowing from modern Latin sacculus, which is itself a diminutive form of the Latin saccus, meaning "bag" or "sack". The root saccus can be traced further back to Greek sakkos, meaning "bag made of coarse cloth or hair", and likely has Semitic origins, possibly from Hebrew śaq or Phoenician śq. The addition of the Latin diminutive suffix -ulus precisely shapes the meaning from a general "bag" to a "little bag". This etymological logic is perfectly preserved in modern anatomical terminology, where the saccule is defined as a small, sac-like structure within the inner ear.
Analysis
Structure: sacc (bag) + ule (small)
- sacc: From Latin saccus, meaning "bag, sack". It functions as the root, providing the core meaning of a bag-like container.
- ule: A diminutive suffix of Latin origin (-ulus, -ula, -ulum), indicating a small version of the root concept.

A pathological dilation of the saccule can be associated with certain inner ear disorders.
