| Sarna | The sacred grove — a stand of the original sal forest left uncleared beside a village, in which the village deities are seated and no tree may be cut. Also the name used for the religion practised in it. |
| Jaher and jaher era ᱡᱟᱦᱮᱨ | The Santali term for the grove, and Jaher Era, the goddess who lives in it, worshipped alongside Marang Buru, the great mountain. |
| Bonga | Santali and Mundari for a spirit or deity — of a grove, a hill, a stream, a house or an ancestor. Ritual life is transactional with bongas rather than devotional towards them. |
| Naeke and pahan | The village priest — naeke among the Santal, pahan among the Munda and Oraon. He conducts the grove sacrifice, fixes the festival dates and, at Sarhul, reads the water pots for the coming monsoon. |
| Manjhi haram | The Santal village headman, working with a council of named officers — paranik, jog manjhi, godet — each with a defined role at weddings, disputes and hunts. |
| Munda and manki | The Ho and Munda system of village headman (munda) and cluster headman (manki), formally recognised in Kolhan since the nineteenth century and still functioning. |
| Parha | The Oraon confederation of villages — a standing inter-village council with its own head, its own flag and its own jurisdiction over disputes between member villages. |
| Khuntkatti | The tenure in which the descendants of a village's original forest-clearing lineage hold its land collectively. Its defence was the central demand of Birsa Munda's movement, and it is written into the Chotanagpur Tenancy Act of 1908. |
| Ulgulan ᱩᱞᱜᱩᱞᱟᱱ | Mundari for "the great tumult" — the name of Birsa Munda's rising of 1899–1900, and now a general word in the region's political vocabulary. |
| Hul | Santali for insurrection, used specifically of the rising of 1855. Hul Diwas is observed on 30 June. |
| Handia and ranu | Rice beer, and the pressed herbal starter cake that ferments it. A ranu recipe is inherited, and the difference between two households' handia is the difference between two ranu recipes. |
| Akhra | The village dancing ground — a levelled open space, usually under a tree, that is also where meetings are held and disputes heard. Every village has one and it is maintained collectively. |
| Dhumkuria and gitiora | The Oraon and Munda youth dormitories, in which the unmarried young of a village slept, worked and learnt song, dance and adult roles under their own officers. The northern counterpart of Bastar's ghotul, and, like it, now almost gone. |
| Rugra and putka | Wild puffball mushrooms of sal root zones, appearing days after the first monsoon storm and impossible to cultivate. |
| Jharkhand | "The forest tract" — jhar, thicket, plus khand, a region. The name appears in inscriptions and land records for centuries before it became the name of a state in 2000. |
