The orthography used in the book is the style recommended by the Yoruba Orthography Committee. Consonants in Yoruba are represented by these symbols: b d f g gb h k l m n p r s ṣ t w y. The consonant gb has no equivalent in English but the g is guttural and pronounced slightly before the b. The consonant p stands for kp in which k and p are pronounced at the same time. The consonant ṣ is pronounced like the English "sh." Non-nasalized or oral vowels include: a e ẹ i o ọ u. The vowel a is similar to the English "ah." The vowels e, i, and o are pronounced like the long a, e, and o in English and u is similar to the English "oo." The vowels ẹ and ọ resemble the English sound "eh" and "aw," respectively. When n appears at the beginning of a word, its sound is similar to the n in English. Adding an n to the oral vowels indicates that the vowel preceding it is nasalized.
