 In a significant recognition of Nigerian culture and language, several Nigerian words and expressions have been officially added to the Oxford English Dictionary (OED), highlighting the global influence of Nigerian English and everyday expressions.

 The inclusion, announced in the dictionary’s December 2025 update, features over 500 new words and phrases from across the world, reflecting diverse forms of English including West African English, Japanese English, and Maltese English.

Nigerian English, known for its rich expressions and colorful street language, was prominently featured in this update.

 Among the newly recognized terms are “nyash,” “mammy market,” “amala,” “moin moin,” “abeg,” “biko,” and the iconic West African phrase “Ghana Must Go.” Each word carries unique cultural significance and reflects everyday life in Nigeria.

According to the dictionary, “nyash” refers to a person’s buttocks, while “mammy market” describes a market traditionally run by women, often found in military barracks, NYSC camps, and educational institutions. 

“Amala” is listed as a dough-like staple food made from yam, cassava, or plantain flour, a dish widely consumed across southwestern Nigeria.

“Moin moin,” also spelled “moi moi,” was included as a popular bean-based dish among the Yoruba people. The expressions “abeg” and “biko” were added as interjections used to convey politeness, urgency, or emphasis in daily conversation. 

Meanwhile, “Ghana Must Go” was defined as the familiar chequered plastic bag used across West Africa, a term historically linked to the 1983 expulsion of undocumented Ghanaian migrants from Nigeria.

Language experts note that the inclusion of these words represents more than just recognition; it underscores Nigeria’s growing influence on global English. 

The country’s linguistic creativity, born out of its multi-ethnic, multilingual society, continues to shape modern English usage both locally and internationally.

This is not the first time Nigerian expressions have made it into the OED. Previous updates have included words and phrases that reflect local culture, humor, and food, highlighting the evolving nature of the English language. 

Linguists argue that such inclusions encourage greater understanding of cultural nuances and promote global awareness of regional linguistic innovations.

For Nigerians, seeing everyday words like “nyash” and “amala” in one of the world’s most authoritative dictionaries is a moment of pride and cultural validation. 

Social media users and language enthusiasts have celebrated the recognition, noting that it showcases Nigeria’s vibrant cultural footprint on the world stage.

As English continues to evolve, the addition of Nigerian words to the Oxford English Dictionary serves as a reminder of the dynamic interplay between language and culture. 

It also cements Nigeria’s position as a key contributor to the global lexicon, ensuring that its unique expressions and traditions gain lasting international acknowledgment.
