Clairvoyant Combatant does not require that you share a language with the target.
It requires that you use the telepathic connection from your level 3 "Awakened Mind" feature on them, but this connection does not require that you share a language. It merely says that to understand each other using that connection, you must share a language. Clairvoyant Combatant does not require that you and the target be able to understand each other.
That said, you actually get three languages to start (Common, and two others) and there a few class and subclass features that provide additional ones. The Dungeon Master's Guide also provides some rules on Training (in chapter 3 under "Marks of Prestige") that allow learning a language via studying with a trainer during downtime.
I have a question on the language and do you need to know it?
I quoted the feature to make it make sense, but it was deleted as spam so I can not describe the feature.
If you have to know a language of the creature, how do you learn more languages? You get 2 at 1st level and I have not found a way to learn more.
