Phi in Kham Mueang: Ghost and Spirit Words
At the end of October many countries dress up as ghosts for Halloween. Ask someone from northern Thailand what phi (ผี) means, though, and the answer is much wider than a spook. The dictionary explains phi as something mysterious and unseen that can bring both good and harm to people, communities, animals and plants. Phi also means a corpse, and it is used for people who behave badly, as in phi phanan, a gambler.
This article gathers the Kham Mueang words that begin with "phi" from the Moradok Lanna dictionary: ancestor spirits, guardian spirits that protect villages and towns, forest spirits from folk belief, and words that start with phi but are not spirits at all, such as the rainbow and the shooting star. Every belief here is told as the dictionary and the cited sources record it, to help you learn the language and understand the culture.
Ancestor spirits: the phi who look after a family
For Lanna people many phi are not things to fear but ancestors who still look after their descendants. The dictionary explains that phi pu ya (ผีปู่ย่า) are a family's own spirits. They hold the kin group together and help settle quarrels. They pass down the female line: when a mother dies, her eldest daughter takes over, and wherever she moves, the phi pu ya go with her.
| Kham Mueang | Lanna script | Meaning (from the dictionary) |
|---|---|---|
| phi pu ya | ผีปู่ย่า | ancestor spirits, the family's spirits, passed down the female line |
| phi kao | ผีเคั้าฯ | the founding spirit of a family line |
| phi ban phi huean | ผีบ้าฯนฯผีเริอฯร | the ancestor spirits of each household |
| phi huean | ผีเริอฯร | the ancestor spirit that protects the people of a house |
| phi mo nueng | ผีหํมฯอฯหึ้นฯง | the spirit of the rice-steaming pot; believed to look after the family, and called on in a divination rite when someone is ill (also phi ya mo nueng ผีย่าหํมฯอฯหึ้นฯง and phi pu dam ya dam ผีปู่ดำย่าดำ) |
| phi mot | ผีม฿ดฯ | ancestor spirits of people of Mon descent in Lanna, paired with phi meng; honoured each year with offerings and dance |
| phi meng | ผีเมงฯ | ancestor spirits of the Mon, or perhaps of the Tai Yuan; danced for in the dry season before ploughing |
| fon phi mot | ฟ้อฯรผีม฿ดฯ | the dance offered to the ancestors, usually in a temporary pavilion before the rice season (fon phi meng ฟ้อฯรผีเมังฯ too) |
| phi khu | ผีระฯคู | the spirits of teachers, such as the teachers of craftsmen, healers, dancers and swordsmen |
Every year the family holds liang phi pu ya (ล้ยฯงผีปู่ย่า), "feeding the ancestor spirits". The dictionary says it is usually held before Buddhist Lent, around the ninth northern month. If someone breaks custom, for example a young man touches a young woman, it is called phit phi, "wronging the spirits". The woman's side must kho su ma (ขํอฯสูมา), ask forgiveness, and the man must sia phi (เสยฯผี), pay a fine in offerings and money set by the woman's family. The full ceremony is described in Liang Phi Pu Ya.

Phi suea: guardians of villages, towns and temples
In Kham Mueang phi suea (ผีเสิ้อฯอ) does not mean the pretty insect. It means a guardian spirit of a place, such as the guardian of a village, a mountain, a town or a temple. These spirits live in a ho phi (หํอฯผี), a spirit house, and villagers make offerings every year to ask for their protection.
| Kham Mueang | Lanna script | Meaning (from the dictionary) |
|---|---|---|
| phi suea ban | ผีเสิ้อฯอบ้าฯนฯ | village guardian, the spirit of the village's founding lord, honoured each year before Lent (also phi mu ban ผีหู่บ้าฯนฯ) |

| liang phi fai | ล้ยฯงผีฝายฯ | the rite of feeding the weir guardian, usually at the end of the rice season |
You can read more about Chiang Mai's guardian spirits in Pu Sae and Ya Sae. Academic work such as Prasit Leepreecha's book Lanna Guardian Spirits: From the Spirit House to the Statue, Shrine and Monument (2017) shows that belief in guardian spirits lives on, moving from wooden spirit houses to statues and shrines today.

Phi ka: a belief to handle with care
The dictionary explains that phi ka (ผีกลฯะ) is the northern name for the phi pop. In the belief, it is a spirit living inside a person; if its host is crossed, the phi ka goes to possess the other person, who then behaves strangely until a mo phi (หํมฯอฯผี), a spirit doctor, drives it out. A fiercer kind is phi ka yak (ผีกลฯะยัก์ขฯ). The bird said to carry the phi ka is nok kao phi ka (น฿กฯเคั้าฯผีกะ), the barn owl or another owl (see Bird Names in Kham Mueang).

Possession, mediums and spirit doctors
Kham Mueang has several words for possession. The dictionary gathers them under phi kum (ผีกุม), a spirit taking over a body so that its owner obeys without knowing it. Phi long (ผีล฿งฯ) is used for a medium who deliberately invites a spirit in.
| Kham Mueang | Lanna script | Meaning (from the dictionary) |
|---|---|---|
| phi kum | ผีกุม | possession by a spirit |
| phi kuam · phi khao · phi tue · phi sing | ผีกวฯม · ผีเขั้า · ผีทื · ผีสิงฯ | words the dictionary refers to phi kum, with the same meaning |
| phi long | ผีล฿งฯ | a spirit entering a medium |
| long phi | ล฿งฯผี | to hold a séance, inviting a spirit into a person to ask about good and bad fortune |
| ma khi | ม้าขี่ | a spirit medium, the person a spirit enters |
| mo phi | หํมฯอฯผี | a spirit doctor who uses spells to invite, drive out or subdue spirits |
| kha tha | คาฯถา | a sacred spell or incantation |
| liang phi | ล้ยฯงผี | to make offerings of food and drink to spirits, to avoid harm, ask for luck or fulfil a vow |
The word ma khi, "the ridden horse", is a vivid one: the medium is the horse the spirit rides. Calling a person's soul back is a different rite, described in Hong Khwan.
Phi tai: words for different kinds of death
Phi tai (ผีตายฯ) means a corpse or a dead person. Kham Mueang has separate words for deaths seen as out of the ordinary. Use them with care and respect for the dead.
