What does indo mean as in Indonesia?

The name "Indonesia" is derived from the Greek words "Indos", meaning "India" or "Indian" and "Nesos" meaning "island", therefore the name literally translates to "Indian Island". The term Indonesia was first used in the 18th century by European geographers to refer to the region now known as Indonesia. The term was popularised in the 19th century by European scholars, and was officially adopted as the name of the country in 1945 when Indonesia became an independent nation.
