羽（yu）
Name meaning
羽 (Yu) means feather or wing, giving a light, free and martial-classical image depending on context.
Practical naming use
羽 (yu) is a feather-and-wing character. It gives a name lightness, lift and classical elegance, so the result feels agile rather than flimsy. It is especially useful for clarity, strength, unisex names, because the character can carry a recognizable Chinese image without becoming empty dictionary filler. The best results come when the second character adds human direction, warmth, restraint or breadth, so the full given name feels lived-in rather than generic.
Pair 羽 (yu) with characters such as 宁 (ning) for calm lift, 文 (wen) for elegant bearing, 清 (qing) for airy clarity or 安 (an) for grounded freedom. The second character should keep the wing image human rather than fantasy-like.
羽宁 (Yuning): Yu contributes feather, lightness; Ning adds peaceful, settled.
