compression

The word 'compression' has a direct and logical lineage from Latin. It originates from the past participle compressus of the verb comprimere, which is a compound of the prefix com- (meaning 'together') and the verb premere (meaning 'to press'). The literal sense is therefore 'the action of pressing together'. This concrete meaning was carried into Middle English via Old French. Over time, the application of the term expanded from physical squeezing to encompass more abstract forms of reduction and condensation, such as in data compression, while retaining the core concept of applying pressure to reduce volume or size.
