Pulaar is a Fula language spoken primarily as a first language by the Fula and Toucouleur peoples in the Senegal River valley area traditionally known as Futa Tooro and further south and east. Pulaar speakers, known as Haalpulaar'en live in Senegal, Mauritania, the Gambia, and western Mali. According to Ethnologue there are several dialect differences, but all are inherently intelligible. Pulaar is written in a Latin script, but historically was written in an Arabic script known as "Ajami script" (see Fula alphabets).
