Etymology
The dish is deeply rooted in Lao cuisine, where it is traditionally called ''tam mak hoong'' (, , ) or ''tam som'' (, , ), in which the word ''tam'' () refers to the pounding of ingredients in a
mortar, a method of preparation central to Lao and neighboring culinary traditions.
In Thailand, the salad is widely known as ''som tam'' (, , ), combining the Thai words ''som'' (ส้ม, "sour") and ''tam'' (ตำ, "pounded"). In Isan, a region with strong cultural and linguistic ties to Laos, the salad uses Lao-derived names ''tam bak hung'' () or ''tam som'' ().
Regional variations and names include:

* Khmer: បុកល្ហុង (''bok l’hong'')
* Rakhine: ပဒကာသီးသုပ် (''pədəɡà θí θùp'')
* Vietnamese: ''gỏi đu đủ'' (a general term for papaya salad, often less spicy)
History
Papayas and
chili peppers were introduced to Southeast Asia by the Spanish and Portuguese explorers in the 17th century from the
Americas
The Americas, sometimes collectively called America, are a landmass comprising the totality of North America and South America.''Webster's New World College Dictionary'', 2010 by Wiley Publishing, Inc., Cleveland, Ohio. When viewed as a sing ...

.
Simon de la Loubère (1642-1729), a French diplomat, mentioned in his book that the cultivation of papaya was already widespread in Siam in 1693.
Although it is unknown when papayas and chili peppers entered Laos specifically, they had already been fully integrated into the Lao territory by the time
Jean-Baptiste Pallegoix and
Henri Mouhot visited in mid-1800s,
[Mouhot, Henri, and Ferdinand de. Lanoye. Voyage Dans Les Royaumes De Siam, De Cambodge, De Laos Et Autres Parties Centrales De L'Indo-Chine: Relation Extraite Du Journal Et De La Correspondance De L'auteur. Hachette, 1868. 322. Print] and were listed among key ingredients for preparing main Lao dishes.
The Lao were introduced to papaya (''mak hung'') from
Khmer Loeu living in provinces bordering the southeastern Laos (who called them ''l'hun'' or ''lohung/rohung'' in Khmer). Papaya, among other fruits, were cultivated in Cambodia in the 1500s.
Green papaya salad was mentioned as a favorite Lao dish by a former Lao politician,
Katay Don Sasorith (1904-1959), in a memoir recounting his experience during his primary school years in 1910s.
Furthermore, according to the travelogue “Nirat Wang Bang Yi Khan” written in 1869 by Thai poet Khun Phum, the dish was already known among members of the Lao royal family living as war hostages in Bang Yi Khan compound in Bangkok, Siam.
Others believe that ''som tam'' has evolved from a Thai dish called ''pu tam or tam pu'' ( หรือ ตำปู, ) mentioned in a recipe by chef, Khunying Plian Phatsakarawong in her 1908 cookbook. This dish shares similarities with modern-day ''som tam'' but does not include papaya as an ingredient.
The earliest known recipe of ''som tam'' in Thailand appeared in the Yaowapha cookbook series by Princess
Yaovabha Bongsanid in 1935, which included ''Som tam ton malako'' () or ''Khao man som tam'' (). This recipe is similar to ''som tam'' as prepared today and includes roasted peanuts and dried shrimp as key ingredients. It is often served with rice cooked in coconut milk.
Preparation

Pounded salads in Laos all fall under the parent category of ''tam som'', which may or may not contain green papaya, however, when no specific type of ''tam som'' is mentioned, it is generally understood to refer to green papaya salad. For absolute clarity, however, the name ''tam maak hoong'' may be used, since this name means "pounded papaya".
In Thailand, it is customary that a customer ask the preparer to make the dish suited to his or her tastes. To specifically refer to the original style of papaya salad as prepared in Laos or Isan, it is known as or ''som tam Lao'' or simply as ''tam Lao'' and the dish as prepared in central Thailand may be referred to as ''som tam Thai''.
Traditionally, the local variety of green papaya salad in the streets of Bangkok is very spicy due to the addition of a fistful of chopped hot
bird's eye chili
