Oxford Dictionary Adds "Nyash," "Amala," and "Ghana Must Go": West African English Goes Official

West Africa Takes the Dictionary

The Oxford English Dictionary's December 2025 update delivered over 500 new words to the English language, but none generated quite the same combination of pride and amusement as the Ghanaian and Nigerian entries that made the cut. Among internet slang like "DM" and "brainfart," the venerable dictionary quietly acknowledged what West Africans have known all along: their words travel.^1

The additions span everyday expressions, food terminology, and cultural artifacts that have become increasingly visible through music, social media, and global migration. "Nyash" - referring to a person's buttocks - now sits alongside centuries-old English words in official lexicographic recognition. The term has particular resonance online, where West African slang circulates through viral content and popular culture.

From Military Barracks to Official Recognition

"Mammy market" earned its place as "a market typically run by women, originally found in military barracks but later also in youth service camps and educational institutions." The term captures a specific West African commercial institution that has no direct English equivalent, making it a genuine addition to the language rather than simply new slang for existing concepts.

The food entries tell their own story about cultural export. "Amala" - defined as "a kind of dough made of yam, cassava, or unripe plantain flour, typically formed into a ball and served as an accompaniment to other dishes" - joins "moi moi," the Yoruba bean pudding that has traveled far beyond its origins.⁴ These aren't just words being borrowed; they represent foods that have established themselves in diaspora communities and beyond.

The Ghana Must Go Controversy

Perhaps the most historically loaded addition is "Ghana Must Go" - the large, chequered plastic bag ubiquitous across West Africa. The dictionary defines it as "a large, zippered bag made of durable plastic with a colourful check pattern," but its origins trace to the 1983 mass expulsion of undocumented Ghanaian migrants from Nigeria.^5 The bag's name preserves a painful moment in West African history, now formalized in the English language's most authoritative reference work.

The Interjection Economy

"Abeg" and "biko" - expressions used to convey politeness, urgency, or emphasis - represent the conversational texture of Nigerian English.⁶ These interjections function as linguistic lubricant in West African communication, softening requests or adding emphasis in ways that standard English "please" doesn't quite capture. Their inclusion acknowledges that Nigerian English isn't simply broken English but a distinct variety with its own grammatical and pragmatic rules.

Building on Earlier Additions

The December update follows a January 2025 addition of 20 Nigerian words and expressions, including "japa" (to flee or relocate abroad), "agbero" (motor park touts), "eba" (cassava meal), "419" (internet fraud), and "abi" (a conversational tag).⁷ Together, these updates represent the dictionary's recognition that Nigerian English has moved from regional curiosity to globally influential variety.

The Oxford English Dictionary also noted contributions from Ghanaian English in recent years, though the December 2025 update focused primarily on Nigerian entries. Earlier additions included Ghanaian terms like "banku" (fermented corn and cassava dough), "azonto" (a dance style), and "galamsey" (illegal mining).⁸

Digital Acceleration

Language experts attribute the rapid adoption of West African terms to digital communication, Afrobeats music, migration patterns, and popular culture.⁹ Social media platforms have compressed the timeline between regional slang and global recognition, allowing Nigerian expressions to circulate internationally within months rather than decades. What once required sustained literary usage or formal documentation now travels through viral tweets, music lyrics, and online conversations.

The update represents more than lexicographic housekeeping. It acknowledges that English belongs to its speakers worldwide, not to its historical centers of power. Nigerian expressions once dismissed as corruption of proper English now hold official status alongside words borrowed from Latin, French, and every other language that has shaped English over centuries.
