noun / verb

hiccup

HIK-up/ˈhɪkʌp/

A sudden, involuntary breathing spasm that makes a short, sharp sound.

Each hiccup briefly interrupts the woman's attempt to sip water.

A compact three-moment sequence shows the same woman experiencing repeated small involuntary torso hitches while trying to sip water, with a relaxed interval between them.
Etymology

The word was formed to imitate the sharp sound produced by the diaphragm’s convulsion. Its sound names the involuntary spasm itself.

In context

The Living Why2:59
The breathing muscles contract first, then the glottis closes almost immediately. That tiny delay makes a hiccup sound like a sharp interruption instead of a normal breath.
