Overbrim

Part of speech: verb

Definitions

1. To fill or overflow beyond the maximum capacity of a container or to exceed the natural limits of something
2. To surpass the normal edge of a vessel or to extend beyond the natural boundaries of an object
3. To exceed the limits of an object, causing content to spill over or rise above its confines

Etymology: "Overbrim" is a plain compound: the prefix "over-", meaning above or beyond, joined to "brim", the edge or rim of a vessel. Put together, the verb describes liquid rising past the lip of a container, and the image is almost literal in the word itself. The same pattern gives us many other English verbs in "over-", such as "overflow" and "overspill", though "overbrim" leans especially on the picture of a full cup or bowl. "Brim" is the older and more basic half of the pair. It is an ordinary English noun for the rim of a cup or the top edge of a container, and it has long been used both for a vessel's lip and, by extension, for anything filled right up to its limit. Because the base is so concrete, the compound keeps that sense of physical overflow rather than drifting into abstract talk of excess.
