Lamma Island got named Lamma only because of a chart reading error by Alexander Dalrymple in the 1760s. He had acquired a Portuguese chart to the entrances to the Pearl River and, close to the west of the island, the Portuguese owner had written “Lama”. Dalrymple misinterpreted that as the name of the island. However, it was a Portuguese notation as to the holding (consistency of the seabed from the point of view of anchoring there), which was (and is) mud ? in Portuguese “lama”.
