天（tian）
Name meaning
天 (Tian) carries sky, heaven and an immense natural scale beyond the human frame. In a name it suggests breadth, clarity and confidence under something larger than the self.
Practical naming use
天 (Tian) is useful when a name needs sky, heaven, natural breadth rather than a generic pleasant sound. Its register is sky, classic, so it can support a boy name that feels culturally legible, visually compact and easy to explain. The character should be paired with a second character that gives the image a human scene: learning, calm action, public responsibility, graceful movement or long-range aspiration.
Pair 天 (Tian) with characters that soften or complete its core image. Bright partners make it more optimistic; scholarly partners make it more literate; water or nature partners make it calmer; virtue partners make it more formal.
天安 (Tianan): Tian contributes sky, heaven; An adds peace, safety.
