The language of the earliest Lithuanian writings, in the 16th and 17th centuries, is known as Old Lithuanian and differs in some significant respects from the Lithuanian of today.
Besides the specific differences given below, it should be noted that nouns, verbs and adjectives still had separate endings for the dual number. The dual persists today in some dialects. Example:
| Case | "two good friends" |
|---|---|
| Nom-Acc | dù gerù draugù |
| Dat | dvíem geríem draugám |
| Inst | dviem̃ geriem̃ draugam̃ |
