half-open

Neither shut nor wide

Half-open describes something partially open—a door, window, or eye that is neither fully closed nor fully wide.

The term appears in technical contexts: in music, a half-open hi-hat produces a distinctive sizzling sound; in mathematics, a half-open interval includes one endpoint but not the other.
