Emeritus Professor Ayo Bamgbose is gone, and Nigeria’s academic world is left to sit with a silence it has not known in a long while. He was born in Odopotu, a small community near Ijebu Ode in present-day Ogun State, on 27 January 1932, and he died in Ibadan on 25 July 2026, at 94, after a life so long and so full that it is difficult, even now, to know where to begin mourning him. We remember him as Nigeria’s and Africa’s first Professor of Linguistics, but that title, however historic, was never the whole man. He was a boy who lost his father too early, a pupil-teacher who studied by correspondence in the evenings, and, in time, the scholar who gave the Yoruba language a grammar and a written form of its own. It is that whole man, with the highest academic and intellectual award in Nigeria, that we gather here to honour.
Odopotu, 1932–1951: A Boy Who Nearly Didn’t Get the Chance
He was the son of Rev. Sangodipe Bamgbose, a community leader in Odopotu, and he had passed his secondary school entrance examination and been admitted when his father died, throwing his education, and, by his own account, everything he had hoped for, into doubt. He refused to let it end there. He sat the entrance examination into a teachers’ training institution instead, was admitted to St. Andrew’s College, Oyo, in 1948, and qualified as a Grade Two teacher in 1951. Through the 1950s he taught in primary, secondary and teacher-training colleges, studying by correspondence in whatever hours were left to him, carrying a grief he never fully set down but never let stop him either.
“Because my father had died, continuing my education became difficult. However, God was with me.”
University College, Ibadan, and Edinburgh to a Chair, 1957–1968: Building the Scholar and the Five-Year Climb
The years between teaching and professorship are too often skipped over, but they are where the discipline was actually built. On a Western Nigerian Government Scholarship, he entered University College, Ibadan, then affiliated to the University of London, in 1957, and in 1959 attended the University of London’s Summer School on a University of Ibadan Fellowship. In 1960 he graduated with a high second-class upper-division B.A. (Hons) in English. He then proceeded, on a University of Ibadan Postgraduate Scholarship, to the University of Edinburgh, where he earned a Diploma in General Linguistics in 1961 and, in 1963, his PhD, with the thesis A Study of Structures and Classes in the Grammar of Modern Yoruba. It was, by his own admission, not the path he had first imagined for himself — as a young teacher he used to sit in on court proceedings, fascinated by the advocacy of lawyers, and once considered law before deciding it was simply beyond his means.
“I would probably have become a lawyer… Unfortunately, I couldn’t pursue that dream because I simply didn’t have the financial resources.”
In 1963, the same year he completed his doctorate, he joined the University of Ibadan as a Lecturer. He became Lecturer I in 1964, Senior Lecturer in 1966 — serving concurrently as Sub-Dean of the Faculty of Arts from 1966 — and, in 1968, at only 36, a full Professor: Nigeria’s first Professor of Linguistics. He was not even at home when the news of his promotion arrived; he returned to find his colleagues already celebrating on his behalf. We say this plainly because it deserves to be said plainly: a man who began as a Grade Two teacher, with no money and no patronage, climbed from Lecturer to full Professor in exactly five years, on the strength of his scholarship alone.
“I joined the university as Lecturer II in 1963… Rising to professorship within five years was extremely rare.”
1966–1990: The Grammar He Gave Yoruba
This is, perhaps, the part of his life we owe him the most care in telling, because it is the part that outlives every title he ever held. Before Bamgbose, Yoruba had never been studied on its own terms with the rigour that European languages routinely received. His 1966 monograph, A Grammar of Yoruba, published by Cambridge University Press, changed that: it applied modern linguistic theory directly to the structure of Yoruba, its phonology, its tone system, and its syntax, describing the language as it actually behaved, rather than forcing it into frameworks built for English or French. Out of that work came concepts the field still uses without a second thought: the assimilated low tone, verb-nominal collocation, lexical matching, the modifying serial construction, and original vocabulary he had to invent because no one had needed those words for Yoruba before. Then, in 1990, he turned to a different, quieter problem: Fonologi ati Girama Yoruba tackled the difficulty of teaching Yoruba grammar to Yoruba students in their own metalanguage, closing the gap between how the language was analysed by scholars and how it was actually being taught in classrooms. Between the two books sits the whole of his gift to the language, he gave it a science, and then he gave that science back to its own speakers.
“It is undoubtedly true to say that since 1963, no one has published anything of significance on Yoruba grammar without reference to and acknowledgement of Professor Ayo Bamgbose’s seminal works.”
His Orthography Reform
It is not enough to say he described Yoruba scientifically; he also decided, quite literally, how it would be written. Before his intervention, written Yoruba carried the uneven, sometimes arbitrary spelling and tone-marking inherited from early missionary transcription. In 1965 he published Yoruba Orthography, a linguistic appraisal of the existing script with concrete suggestions for reform, through Ibadan University Press. He then chaired the Western Nigeria Ministry of Education’s Committee on Yoruba Orthography from 1966 to 1969 and edited its Report of the Yoruba Orthography Committee, the document that fixed the under-dots on the open vowels ẹ and ọ and the postalveolar fricative ṣ, settled how high, low, and mid tones would be marked; and resolved long-standing confusion over when compound words should be joined or separated. That is, in essence, the Yoruba orthography still taught in schools today. He carried the same instinct for standardisation beyond Yoruba, chairing the National Language Centre Working Committee from 1968 to 1979 and serving as its consultant linguist on the Wazobia project, work that fed into the wider harmonisation of Nigerian orthographies, Yoruba, Hausa, Igbo, and Efik among them. He also insisted the reform be tested where it mattered most: in classrooms. Through the Ife Six-Year Primary Project, pupils were taught entirely in Yoruba using the newly standardised script, as a result, children were reasoning more confidently and retaining more in a language that was properly theirs. This became the evidence behind his lifelong argument for mother-tongue education.
Building Institutions That Outlive Men
He understood, long before it was fashionable to say so, that scholarship needed structures to survive beyond any one scholar, and he spent much of his life building them. Inside the University of Ibadan itself, he carried nearly every administrative weight the institution could hand him. He served two terms as Head of the Department of Linguistics and African Languages (1969–1975 and 1977–1981), was Dean of the Faculty of Arts (1971–1973), served as Warden and later Master of the Postgraduate Hall, sat on Senate from 1967 to 1978 and on Council from 1986 to 1990, and chaired both the Senate Committee on the General Studies Programme and the Senate Publications Committee. None of this was separate from his scholarship, as Head of Department and doctoral supervisor, he trained a generation of researchers, several of whom went on to become professors and heads of department in their own right, carrying his methods of close, evidence-based analysis into universities across Nigeria and beyond. It is why those who mourn him today so often describe themselves not as admirers but as students.
Professor Bamgbose also extended his administrative service beyond University of Ibadan as he served as the pioneer Secretary-Treasurer of the West African Linguistics Society and later became its President, and he was the founding President of the Nigerian Academy of Letters. From 1999 he represented the St. Andrew’s College Old Boys Association on the Governing Council of St. Andrew’s College of Education, Oyo, work that fed directly into the Academic Brief, which secured Ajayi Crowther University its license in 2005. He then sat on ACU’s inaugural Governing Council from 2005 to 2014 and, as President of SACOBA, led the donation of the SACOBA House and National Secretariat to the university. Governance, in his hands, was never a title to be worn; it was work to be done.
Decades later, in an interview marking his 90th birthday, he was still standing guard over institutional independence, warning against any federal attempt to bypass universities’ own recruitment procedures. For him, autonomy was never an abstraction. It was the difference between an institution that governs itself and one that is merely administered from outside, and he never stopped insisting on the difference.
“University autonomy has always been a critical issue. The more university authorities and lecturers strive to protect that autonomy, the more it appears the federal government is finding ways to circumvent it.”
His idea of governance was never confined to committee rooms. During the disputed 1979 presidential election, he went on national television to challenge the infamous “12 2/3” formula as fraudulent and immoral, insisting that the Electoral College, not dubious arithmetic, should decide the outcome, a courageous stand to take against a military government
A Life of Honours
It would take a whole essay of its own to properly list what came his way, but it is important that we try, because he earned every line of it. In 1984 he became the first African linguist granted honorary membership of the Linguistic Society of America. In 1990, the Federal Government conferred on him the Nigerian National Order of Merit, Nigeria’s highest academic honour, and he was its sole recipient that year. In 2000 he was elected the first African President of the International Association of World Englishes; in 2003, the 2nd Vice-President of the Permanent International Committee of Linguists, again a first for an African linguist. In 2009 he became Foundation President of the Assembly of Academicians of the African Academy of Languages, and in 2010 he was inducted into the Nigerian Academy of Letters’ Hall of Fame for Letters under the NLNG. He held visiting professorships at Hamburg, Cambridge, Illinois, and Leipzig; authored more than twenty books and over 130 scholarly papers; and was still being honoured, at his 90th birthday in 2022, by the Yoruba World Centre, decades after most careers would have quietly ended.
Legacy
Professor Ayo Bamgbose’s name now marks a street at Ajayi Crowther University. His Grammar of Yoruba still sits on reading lists in universities across Africa and beyond, and the orthography he fought to standardise still shapes how the Yoruba language is read and written today. The Nigerian Academy of Letters he founded continues to stand as the country’s foremost house of humanities scholarship. A boy from Odopotu, without a father, without money, and without connections, gave a whole language its grammar and its script and then built the institutions and the scholars to make sure none of it would be lost.
Sun re o, Baba.
