Contiguous

adjective
/kənˈtɪɡjʊəs/
Sharing a common boundary; touching or adjoining at a border without any gap. In international law and UNCLOS, the 'contiguous zone' extends 24 nautical miles from a state's baselines (12 nm beyond the territorial sea), within which the coastal state may exercise control to prevent or punish infringement of its customs, fiscal, immigration, and sanitary laws; for India this zone is established under the Territorial Waters, Continental Shelf, Exclusive Economic Zone and Other Maritime Zones Act, 1976.

✍️ Usage in a UPSC answer

India's contiguous zone, extending 24 nautical miles from the baseline, enables customs and immigration enforcement, effectively serving as a buffer between the territorial sea and the high seas.

🔡 Root

Latin contiguuscontingere (to touch) ← con- (together) + tangere (to touch)

📜 Etymology

From Latin contiguus (touching, bordering), derived from contingere (to touch on all sides). Related to tangent and contact. Entered English in the 17th century as a geographical and legal term denoting physical adjacency.

🧠 Memory Hook

CONTIGUOUS = CONTACT + continuous. Things that are contiguous are in contact, touching. Remember the Continental shelf is contiguous to the coast — they share that Latin tangere (touch) root.

🎯 How This Word Works in UPSC Writing

Sharing a common border or touching along a boundary. It is a precise term in GS1 geography and GS2 federalism, as in contiguous districts forming an administrative unit or contiguous States sharing a river basin. Note that contiguity implies actual contact, so territories separated even slightly are adjacent or proximate but not contiguous.

⚖️ Don’t Confuse It With

Contiguous areas touch along a boundary. Adjacent means near or neighbouring without necessarily touching. Continuous means unbroken in itself rather than touching something else. Enclave is the opposite condition, a territory surrounded by another and not contiguous with its parent State.

🇮🇳 Hindi Meaning

सन्निकट (sannikat) or सटा हुआ (satā huā).
