n. the process of becoming progressively worse

The word traces back to Latin deteriorare ("to make worse"), derived from deterior ("worse"). It entered English via Old French deteriorer in the 16th century, originally describing moral or physical decline. The suffix -ation systematized it into a noun denoting the process of worsening. The core logic hinges on the comparative deterior, reflecting a downward progression from an already inferior state.
