into + [adjective] + territory

Usage Note

Often found in fixed phrases with adjectives: familiar territory, uncharted territory, dangerous territory. Most natural in negative constructions ('not my territory') or directional metaphors ('moving into… territory'). Less natural as a simple positive claim ('My territory is physics'). The fixed phrase 'goes with the territory' means something is an unavoidable part of a situation.

Common Mistakes

Physics is my territory — I teach it at the university.
Physics is my field
I teach it at the university.' — 'territory' in positive claims about expertise sounds unnatural; use 'field' or 'area' instead.

Synonym discussion

Sense: noun/1

Territory (sense 1) describes a geographical area under political or governmental authority, especially one with established or contested boundaries. Domain is broader, covering both literal land and figurative spheres (public domain, private domain), but is less precise about borders and more about ownership or rule. Region simply identifies a continuous area with shared characteristics — it has no inherent sense of control. Zone specifies a place set apart for a particular use or purpose (combat zone, time zone) rather than political jurisdiction. Area is the most generic term, usable in almost any context. For example: 'Canada claimed the northern territory as its own.' (political control). 'The desert region receives very little rainfall.' (neutral geography). 'This is a no-parking zone.' (designated purpose).

Phrases

  • part of someone's territory

  • outside one's territory
  • within someone's territory

Etymology

LatinFrenchEnglish

Territory entered English in the 14th century from Latin 'territorium', meaning 'land around a town' or 'domain'. This Latin noun was formed from 'terra' (earth, land) plus the suffix '-torium' (place connected with). The word came into English through Old French 'territoire'. Its modern political meaning developed from the original sense of an area under a town's jurisdiction.
