Ihmāl—meaning “neglect”—is the technical term in Arabic grammar for omitting the dots from certain letters of the Arabic alphabet. It also refers to the use of a whole range of signs (the ʿAlāmāt al-Ihmāl) to indicate that certain letters of the Arabic alphabet do not carry dots. Ihmāl was first developed in the so-called “new style” of Arabic script that emerged as a bookhand in the 3rd/9th century. “The neglect neglected” refers to the fact that the description and the use of the ʿAlāmāt al-Ihmāl have rarely been object of scholarly research. The subject is treated here according to a historical timeline. A short history of dotting is followed by a description of Ihmāl in full swing; then, variations on the theme are shown; and finally, the gradual disappearance Ihmāl and the shift in function, from orthographical auxiliary sign to ornamental element, are given attention. Several ideas on Ihmāl that have been articulated by scholars of the classical period are quoted.
