How come Starfire speak English perfectly and everyone on Tamaran can?

In the DC Comics universe, the inhabitants of Tamaran possess a unique ability called the "Tamaranean Tongue," which grants them the power to understand and speak any language they come across, including English. This ability is an inherent characteristic of their physiology, and it allows Tamaranians to communicate seamlessly with individuals from different cultures and civilizations.

As a Tamaranean, Starfire naturally possesses this ability and can effortlessly converse in English despite her extraterrestrial origins. This linguistic proficiency enables her to interact with the other members of the Teen Titans, the superhero team she is part of, as well as with humans from Earth.

It's worth noting that the Tamaranean Tongue is a fictional element within the DC Comics universe and does not have a basis in real science.
