Your character knows at least three languages: Common plus two languages you roll or choose from the Standard Languages table. Knowledge of a language means your character can communicate in it, read it, and write it. Your class and other features might also give you languages.

The Standard Languages table lists languages that are widespread on D&D worlds. Every player character knows Common, which originated in the planar metropolis of Sigil, the hub of the multiverse. The other standard languages originated with the first members of the most prominent species in the worlds of D&D and have since spread widely.
