Galach was the official language of the Imperium, and by far the most widely spoken language in the known universe.

It originated primarily from English and various Slavic tongues, along with numerous other ancient Earth languages. As with any language, over the millennia it evolved and adopted various cultural markers.

Galach was spoken in one form or other by the majority of conventional humans, as well as by some genetically altered humans, such as the futars and the Bene Tleilax. Written Galach was generally understood from one planet to another, despite regional dialects.

Several groups spoke Galach in addition to specialized languages (e.g. the Atreides Battle Language) and arcane variants (e.g. the native Fremen language). Other groups spoke Galach in addition to ancient Earth languages or older largely obsolete languages like Chakobsa. An example of this was the Bene Gesserit Sisterhood: Reverend Mothers periodically spoke old French.
