The ingenious assemblage of A Dictionary of Yoruba Monosyllabic Verbs is chief among Chief Isaac Oluwole Delano’s contributions to the lexicography of the language. The laborious effort of documenting and entering the unique lexical items into a single voluminous text for the Institute of African Studies of the then University of Ife (now Obafemi Awolowo University) in Ile-Ife is a historical undertaking. No one before or even after Delano has attempted a dictionary of this magnitude, let alone of the Yoruba monosyllabic verbs.
