Language is the ability to acquire and use complex systems of communication and a language is any specific example of such a system. The scientific study of language is called linguistics. There are over 6000 languages of Earth alone, with millions throughout the Marvel Universe.
Most Marvel Comics are written in variation of English known as "American English."
In most instances during which a character is speaking in another language and the reader is meant to know what they're saying, said character's dialogue in their speech bubble will be written in American English between angle brackets ("<" and ">"), which indicates that said character is talking in another language. The first use of angle brackets is usually accompanied by an asterisk and an editor note box stating what language it the dialogue being translated form.
In other occasions, speech bubbles with text in another language may feature narration boxes next to them, which translate said dialogue. In less common cases, dialogue spoken in languages may not be translated at all.
When foul language is censored, the word (or words) in question is usually replaced with a standard grawlix ("#$%&").

- Lockheed can understand what one is saying regardless of language; he knows several human and alien languages and speaks English, but rarely does so.
- Professor X using his telepathy can understand all languages, he can download the knowledge into his mind or to others. When he sends the X-Men on a mission with short-duration language programming, mostly by reading the minds of people in the area they're visiting. Recent examples have included:

- When the team went to Japan for Wolverine's wedding to Mariko Yashida, he likewise taught them Japanese.
- Sleepwalker, learned to speak English because that's the language his human host speaks. If Sleepwalker had been trapped in the mind of someone who spoke another language, like French or German, he would have begun using that language when he first appeared in the human world.
Many alien species have visited earth and have been able to use signals from various forms of entertainment and communication to learn the native language:
- Shatterstar possesses enhanced learning capabilities and mastered Spanish by watching television.

- Due to constant contact with alien races Reed Richards invented a Universal Translator.
- The Nova Corps use specially designed Nova Helmet's that can translate languages from different species.
- In the galactic communities such as the Kree Empire; Translator Implant's are commonly used. Star-Lord has one attached to his neck.
- On the planet Sakaar the slaves are attached with a Obedience Disk which keeps them in check and contains tiny robots called "Talkbots" this allows instantaneous translation of any language.
- The Power Pack has universal translators built into their uniforms.
All Asgardians, and other deities in the Marvel Universe, can speak every language thanks to the "Allspeak" or "All-Tongue", in which what they say is understood by every species in their own native language.
The Marvel Universe has various alien languages based on cypher codes. The code usually works using English usually, a substitution cipher with the same words, grammar and all. Typically, an entirely new 26 letter alphabet is invented. A few examples are:
- Doopspeak; the language used by Doop.
- Builder Machine Code: used by the Builders race and it's creations.
- Demonic Script; used by the Demons of Limbo.
