Burmese names lack the serial structure of most Western names. The Burmans have no customary matronymic or patronymic system and thus there is no surname at all. In the culture of Myanmar, people can change their name at will, often with no government oversight, to reflect a change in the course of their lives. Also, many Burmese names use an honorific, given at some point in life, as an integral part of the name. Traditional and Western-style names Burmese names were originally one syllable, as in the cases of U Nu and U Thant ("U" being an honorific). In the mid-20th century, many Burmese started using two syllables, albeit without any formal structure. In the late 1890s, British scholars observed that Rakhines commonly adopted three-syllable names whereas Burmans were still using one or two at most. As they become more familiar with Western culture, Burmese people are gradually increasing the number of syllables in their children's names, by use of various structures. Today, names with up to four syllables are common for men and up to five for women. Scholars such as Thant Myint-U have argued that the rise of complex Burmese personal names resulted from the collapse of the Burmese monarchy, which ended the sophisticated system of Pali-Burmese styles, crown service and gentry titles, leaving the majority of Burmese with single-syllable names. Former titles, such as min (; "leader") were re-appropriated as part of personal names. For example, Burmese nationalist Aung San's parents were named Pha () and Suu (), both of which are single-syllable names. His birth name was Htain Lin (), but he changed his name to Aung San () later in life. His child is named Aung San Suu Kyi (). The first part of her name, "Aung San", is from her father's name at the time of her birth. "Suu" comes from her grandmother. "Kyi" comes from her mother, Khin Kyi (). The addition of the father or mother's name in a person's name is now quite frequent, although it does not denote the development of a family name. Other nomenclature systems are used as well. The use of the names of one's parents and relatives in personal names , although it differs from historical Western practices. Burman names commonly include Pali-derived words combined with native Burmese words, including: Female: sanda ( "moon", from canda) thanda ( "coral", from santa) thiri ( "splendour", from siri)
