A variant of Ilan, the Hebrew word for tree.
Ilaan is a variant of Ilan, the Hebrew word for tree. That botanical root gives the name a calm, natural quality, with the tree standing as a symbol of life, rootedness, and growth.
The spelling makes Ilaan feel a little more extended and contemporary than Ilan, but it preserves the same simple nature image. It is a name with quiet strength: short, clear, and grounded in one of the oldest and most universal symbols. In modern use, that combination of simplicity and meaning gives it an understated appeal.
