Every settlement name in Puducherry is a compressed archive — encoding caste identity, ecological memory, colonial encounters, and religious geography into 2–3 syllables. This section maps the full suffix taxonomy with live OSM data.

| -pakkam | பாக்கம் | Quarter / neighbourhood | Brahmin suburb Dalit quarter | Tamil | Medium | Peripheral to main ur |
| -pettai | பேட்டை | Market / bazaar town | Merchant castes | Telugu peta | Medium | Trade routes, road junctions |
| -palayam | பாளையம் | Military camp / poligar grant | Warrior / Mudaliar | Tamil pālai | Low-Med | Outskirts, garrison periphery |
| -kudi | குடி | Clan homestead | Vellalar / OBC | Tamil | Low | Agricultural interior |
| -nagar | நகர் | Modern planned suburb | Mixed — often SC renamed | Sanskrit nagara | High (post-1947) | Urban fringe, SC colonies renamed |
| -medu | மேடு | Elevated mound | Fisher / coastal | Tamil | Low | Coastal elevated ground |
| -kulam | குளம் | Tank / water body | Vellalar (tank control) | Tamil | Medium | Near historic water bodies |
| -kuppam | குப்பம் | Fishing hamlet | Paraiyar / Mukkuvar | Tamil | Medium | Coastal margins, downwind |
| -agraharam | அக்ரஹாரம் | Brahmin-only gifted street | Brahmin exclusive | Sanskrit agra+hāra | Low | Temple-adjacent, central |
| -cheri | சேரி | Segregated colony | Dalit (SC) | Tamil | Medium | Village margins, downwind |
| -salai | சாலை | Road / highway | Colonial / French | Tamil (via Arabic) | Medium | French-planned road grid |
| -kovil | கோவில் | Temple settlement | Temple community | Tamil kō+il | Low-Med | Ritual centres |
| -palli | பள்ளி | Mosque / school / rest | Muslim / Jain / Buddhist | Sanskrit pallī | Low | Muslim quarters, old trade routes |
Do historically oppressed caste settlements appear at the spatial margins of villages? This map tests that hypothesis by plotting settlement-name typologies against each other, revealing the concentric ring structure of caste space.
In Puducherry's coastal villages, Dalit -cheri and -kuppam settlements cluster on the eastern/northern margins — historically downwind from the main ur, near cremation grounds and waste-disposal areas. This spatial encoding is readable in name distribution alone.
Brahmin -agraharam streets are invariably located adjacent to the main temple, forming a sacred geography where proximity to ritual space = social power. In Villianur, Bahour, and Ariyankuppam, this pattern is still visible in OSM building data.
Vellalar dominance in the Puducherry hinterland is encoded in -kulam (tank) toponyms. These settlements controlled irrigation infrastructure. Their names appear in Chola copper plate grants — land that was physically and nominally theirs for centuries.
Place names preserve ecological memory that satellite imagery has forgotten. -Eri (lake), -kulam (pond), -pallam (depression), -kadu (forest), -medu (mound) names reveal a hydrological landscape that has been drained, built over, or erased. Overlaying toponyms against current satellite data reveals these ghost geographies.
Settlement names containing -eri (lake/tank) where OSM shows no current water body. These represent historically drained or urbanised waterbodies — critical for flood-risk and ecological restoration planning.
Tamil kādu (forest/wilderness) survives in street and locality names within fully urbanised Puducherry town. Each -kadu toponym is a fossilised forest marker — the tree cover existed within living memory of the name's coinage.
-Medu (elevated mound) often marks ancient settlement mounds — archaeological sites where previous occupation layers raised the ground level. Fishing communities settled these elevated spots for flood protection. Cross-referencing with ASI survey data reveals buried sites.
Puducherry's French colonial period (1674–1954) created one of South Asia's most documented segregated urban geographies. The Ville Blanche (White Town) / Ville Noire (Black Town) division was a deliberate spatial technology — enforced by canal, road grid, and naming convention.
The French quarter east of the canal was planned on a Cartesian grid — straight streets, stone buildings, churches, the Governor's Residence. Street names were French: Rue de la Marine, Rue Dumas, Rue Suffren. The Promenade (Beach Road) was for European leisure. Tamil and Indian residents were legally excluded from night residence in the White Town until the 1880s.
French street names persist in OSM today: Rue Romain Rolland, Rue Suffren, Rue de la Marine. These are not just nostalgic — they mark the former European exclusion zone.
West of the canal, the Tamil city grew organically along caste lines. Street names here encode social hierarchy: Brahmin Street, Mudali Street, Vannara Street (washermen), Ambalakar Street. The French administration mapped and froze this caste geography into the street grid, making colonial segregation and caste segregation mutually reinforcing.
OSM still shows "Brahmin Street," "Vannara Street," "Ambalakar Street" in Black Town — the French cartographic encoding of caste persists in municipal records.
Cross-referencing caste-coded settlement toponyms with OSM infrastructure layers (bus stops, schools, hospitals, street lamps, roads) reveals whether spatial marginalisation in names correlates with real infrastructure inequality.
OSM query for bus_stop nodes within 500m of -cheri/-kuppam settlements vs -puram/-nagar settlements shows a marked disparity. Dalit hamlets on the margins are the last to receive public transport — a spatial inequality that compounds social exclusion.
Primary school density correlates with upper-caste settlement history. Brahmin -agraharam localities have inherited the mission and government school infrastructure built in their zone; -cheri settlements rely on single-room schools added post-1960 under SC welfare schemes.
OSM highway tags (surface=unpaved/dirt) cluster in settlements bearing Dalit-associated suffixes. While this data is incomplete in OSM, the pattern is consistent with ethnographic fieldwork data from Gorringe (2005) and Mosse (1994).
