Borotiam (pronounced as "Borosiam") is named after Belgium. Kiribati and Belgium have shared a historical tie which began with a Belgian missionary who arrived in Kiribati over a hundred years ago. He was so loving, devoted and committed to his congregation, that the people were deeply touched and decided to name their village as Belgium.

In the vernacular, this was written as Borotiam, a name which has been kept to this day as a symbol of the everlasting appreciation for the Belgian sacrifice that had contributed significantly to the progress and wellbeing of Kiribati.
