Usage of ～島
The suffix ～島 (とう) is used to denote islands, often attached to place names to specify a particular island. It is common in geographical names across Japan and other contexts involving islands.

Nuances and Usage Notes
When you see ～島 attached to a name, it usually refers to a specific island rather than just the concept of an island. For example, 沖縄本島 (Okinawa Main Island) refers to the main island of Okinawa Prefecture.
This suffix is mostly neutral in formality and used in both spoken and written Japanese, especially in geographical or travel contexts.
Common Mistakes
Learners sometimes confuse ～島 with 島 alone. The suffix ～島 is often part of a compound noun and is not used independently. Also, the reading is usually とう in compounds, not しま, which is the standalone reading for 島.
