Etymology
The word 'cache' entered English in the late 18th century from French, specifically from the verb 'cacher', meaning 'to hide'. This French term evolved from the Vulgar Latin 'coacticare', a frequentative form of the Latin 'coactare', which meant 'to constrain or store'. The core semantic thread from Latin to modern English is the concept of putting something away under pressure or into confinement, leading to the idea of a secret storage place. In the 20th century, this concept was perfectly mapped onto computer science to describe a high-speed storage layer that 'hides' copies of data for quicker retrieval, seamlessly extending the original meaning into the digital realm.
Analysis
The entire word 'cache' functions as a simplex morpheme. It is a loanword from French, where it serves as a noun meaning 'a hiding place' and is derived from the verb 'cacher' ('to hide'). Its ultimate origin is the Latin verb 'coactare', meaning 'to force together, compress, store'.
