Embouchment

/ɛmˈbuːʃmənt/ noun

Definition

The act or process of forming or shaping something into a mouth-like opening or the outlet where a river meets the sea.

Etymology

From French 'embouchement,' derived from 'emboucher' meaning 'to put in the mouth,' from 'em-' (in) + 'bouche' (mouth), from Latin 'bucca' (cheek, mouth). The meaning evolved to describe geographical features where water flows outward.

Kelly Says

River deltas and estuaries are perfect examples of embouchments—they're where rivers literally 'open their mouths' into the ocean, and this geological feature has shaped human civilization for millennia, from the Nile to the Amazon.
