Overview

An adjective describes a noun e.g. hot chocolate.

This means that it needs to have the same set of grammatical endings as the noun. It will agree with the noun it qualifies in gender, case and number.

Uses

Adjectives can be used in two main ways.

Attributive

An attributive adjective is one that simply describes the noun,

The brave soldier walks into the house
which in Latin would be:
miles fortis in villam ambulat.

Predicative

A predicative adjective is used with the verb 'to be' and completes a sentence about the noun,

The soldier is brave
which in Latin would be:
miles est fortis.

Word order

In prose, Latin adjectives usually come after the noun.

miles fortis
the brave soldier

Exceptions are adjectives to do with quantity and size,

magnus miles
the great soldier

Other notes

There is not always a noun for the adjective to qualify. In this case, you can supply a noun. The most frequently found unstated nouns are, according to the gender and number of the adjective:

Masculine Man/men
Feminine Woman/women (but also sometimes 'hand(s)' or 'house'
Neuter Thing(s)
