The word
Baucau is derived from the word "Akau", which means "pig" in the local
Waimoa language. During the
Portuguese colonial era, the name of the district was transformed, first into
Macau and finally into
Baucau. An alternative name for the Baucau community is
Wailia-Wailewa, meaning the "great water spring of Wai Lia". In 1936, the Portuguese colonial authorities renamed what was then the district of Baucau as "São Domingos". However, that name, like other imperial-sounding names adopted in the colony at about that time, did not catch on, and a few years after
World War II it was quietly abandoned. ==Geography==
