Human languages (Earth-5875)

Humans have a plethora of languages used to communicate between each other. Being a space-faring species, many of their languages were spread through colonies. By the 30th century, English serve as the primary language of the Unified Earth Government, which is widely spoken through human-controlled space, but despite this, many other languages are still used with secondary roles in society. Through human's historical contact with aliens, such as the Covenant and the Cabal, members of the respective empires studied and learned English to interpret human communication. The VISR for MJOLNIR GEN2 features a translation software with the data of hundreds of human languages.

English
English is a language of West Germanic language origin, which first appeared in England. During most of human history, it was also the first language of Australia, Canada, Ireland, New Zealand, the United Kingdom, and the United States of America, all encompassing what was known as the Anglosphere. By the 21st century, English started to become more widespread with globalization, and by the 26th century, it became the lingua franca of the Unified Earth Government and humanity as a whole, both on Earth and its colonies.

Unggoy, kig-yar, sangheili, jiralhanae, san'shyuum and xenomorphs (only with the formation of a Gravemind), are the only species able to speak English; yanme'e, lekgolo and huragok are unable to speak human languages duo to their biology.
