the.com/isle

means A small island, especially one small or distinct enough to have its own name.

from From French 'isle,' from Latin 'insula' (island) — the same root that gives us 'insulate' and 'peninsula.' The 's' was actually silent and dropped in pronunciation centuries ago, but Renaissance scholars, showing off their Latin, stuck it back into the spelling of both 'isle' and 'island' to make them look more classical. The twist: 'island' never had a Latin 's' to begin with — it comes from Old English 'igland,' unrelated to 'insula' — so that silent 's' is a pure spelling-snob flourish, not an etymological fact.
