By Sound
Aiden (AY-duhn) opens on a sound Mandarin handles well — 艾 or 蔼 both land close to Ai- — while the ending leans on characters like 登 or 阳 rather than chasing an exact match for the trickier -den close.
By Meaning
Aiden comes from the Irish Aodhán, meaning little fire. It's a name about a small, warm spark — not a blaze, something steadier and gentler than that.
By Spirit
Aidens tend to be easy to like — socially fluid, warm without being intense, the kind of presence that makes a room feel more comfortable rather than more exciting.
