Infundibuliform

It looks like a made-up word.

But thanks to A Word A Day
I know that it's all too real:

MEANING:
adjective: Funnel-shaped.

ETYMOLOGY:
From Latin infundibulum (funnel), from infundere (to pour in), from fundere (to pour). Ultimately from the Indo-European root gheu (to pour) that is also the source of funnel, font, fuse, diffuse, gust, gush, and geyser.
