Elfin describes something small, delicate, and graceful in a way that reminds people of elves from fairy tales and fantasy stories. An elfin face might have fine, delicate features and a slightly mischievous expression. A ballet dancer moving across the stage might have an elfin quality in her light, quick movements.

When you call someone's appearance elfin, you're noticing something charming and fairy-like about them: maybe small, pointed features, a petite build, or an otherworldly grace.

You might describe a child with bright eyes and delicate features as having an elfin face, or notice how someone's elfin fingers move quickly and precisely when playing the piano. The word carries a sense of something both magical and a bit impish. It's usually a compliment, suggesting someone or something is both beautiful and intriguing in an unusual way.
