How to Decline Latin Demonstrative Pronouns: Hic, Ille, Iste, Is

If you are learning Latin, whether for your work in biology and medicine, science or law or as a classicist, or if you are studying for your SAT or ACT, this table of demonstrative pronouns will prove to be a useful resource.

Latin Pronouns

As in almost every language, pronouns are key to the language, standing in conveniently for nouns, proper nouns and noun phrases. There are seven classes of pronouns but three that stand out as the main categories of pronouns in Latin: personal pronouns ("I, you [singular], he, she, it, we, you [plural] and they"), demonstrative pronouns ("this, that, these, those") and relative pronouns ("who, which").

Demonstrative Pronouns and Adjectives

Demonstratives as a whole point out or designate a person or thing for special attention. Demonstrative pronouns, like nouns, can stand alone, but demonstrative adjectives can't. The forms are the same for both demonstrative pronouns and adjectives in Latin, but a demonstrative adjective needs a noun to modify and the two are usually in close proximity.

Hic means "this" when used as a demonstrative pronoun; ille and iste mean 'that'. Hic, as a demonstrative adjective, still means "this"; ille and iste still mean "that." Is is a fourth, weaker demonstrative, known as "determinative." As with most rules of grammar, there can be exceptions.

Declensions of Demonstratives

Declining nouns, pronouns and adjectives is a lot like verb conjugation. We identify the root of the word and add endings for agreement. For nouns, pronouns and adjectives, the endings indicate the grammatical gender, case and number of the noun.

1. Gender can be masculine, feminine or neuter.
2. Case includes nominative (subject of the verb), genitive (possessive or to be "of" something), dative (to be "to" or "for" something, accusative (the object of the verb) or ablative (to be "by," "with" or "from" something). 
3. Number indicates whether the noun is singular or plural.

You'll see all three in the tables below of demonstrative pronouns.

How to Remember Declensions

Declensions are absolutely essential. You have to know them in order to understand Latin. What's a good way to remember pronoun declensions? One reader on Quora.com says his Latin teacher made the class learn "through recitation. The faster it gets, and the more often you do it, [the more] it sticks, it really does." After 15 years, he says, he still knows entire declensions, even though he hasn't recited them in almost as long. But others warn to try not to learn all of the endings at once. First look for patterns, which can add logic to the process and make remembering easier.
