Etymology

fortress = fort<strong> + ess<noun suffix denoting place>

  • fort (from Latin fortis, meaning "strong")
  • ess (a suffix derived from Latin -itia or Old French -esse, indicating a place or state)

Etymology Origin:
The word "fortress" traces back to Latin fortis ("strong"), combined with the suffix -itia (later adapted into Old French as -esse), which denotes a place or condition. Originally used in Old French (forteresse), it entered Middle English to describe a heavily fortified structure. The morpheme "fort" retains its core meaning of strength, while "-ess" transforms it into a physical or symbolic place of security. This reflects the logical progression from "strength" to "a stronghold."
