Generally, a tribe is divided into two or more sections. In a tribe with two sections, each section is called a moiety. Tribes with more than two sections refer each of these divisions by the term 'phratry'. Moieties and phratries are, generally, exogamous, that is, spouses are found from outside the social divisions. In some societies, e.g., the Toda, moieties are endogamous, that is, members ofthe moieties must marry within the division.
