Human language
Human languages were languages spoken and used by Humans (and some aliens), composed of numerous branches and dialects that all originated on the planet Earth.

In 2364, after hearing Lore refer to Data as "imperfect", Jean-Luc Picard confessed he found the description troubling. Data then attributed it to Lore's potential inability to use Human language well – something he struggled with, too – suggesting the term "imperfect" might simply refer to Lore having certain abilities that Data was lacking.
