Latin demonstrative pronouns
Latin demonstrative pronouns have a declension similar to adjectives. The most characteristical feature distinguishing them is gen.sing. of all genders in -ius and dat.sing. in -i. In nom.acc.voc. of the neuter gender there is an ending -d instead of -m. Most frequent pronouns are hic, haec, hoc and is, ea, id
Pronoun hic, haec, hoc
This pronoun is very irregular. It has an additional element -c in whole singular (except genitive). Its nominative is also untypical. In plural, it loses -c and it is regular except one form (nom. acc. voc. neutrum haec).

| gen. | horum | harum | horum |

Pronoun is, ea, id
Except two forms is and id, this pronoun has e-, to which regular endings are added. Instead of eis, the form iis is very often used in plural.
