Rare diminutive possibly from French 'île' (island) or a variant of Islet.
Ilet is a rare diminutive that may come from French ile, meaning island, or be related to the word islet. Either way, it carries a small, secluded, and place-based feel that makes it unusually delicate.
Its brevity is part of its appeal. Ilet sounds quiet, compact, and lightly nautical or geographic, as though it belongs to a tiny landform seen from the water. The name has an understated charm that comes from suggestion rather than explanation.
