Evolution of the English pronouns

The English language once had an extensive declension system similar to Latin, modern German or Icelandic. Old English distinguished between the nominative, accusative, dative, and genitive cases; and for strongly declined adjectives and some pronouns also a separate instrumental case (which otherwise and later completely coincided with the dative). In addition, the dual was distinguished from the more modern singular and plural
