In the first half of your first year of studying Latin, you will learn six syntax rules.
Rule 1: The subject–object rule
The subject of a sentence will be in the nominative case; the object of a verb will be in the accusative case.
Rule 2: The subject–verb agreement rule
If the subject of a sentence is singular, the verb must be singular; if the subject of a sentence is plural, the verb must be plural.
Rule 3: The preposition phrase rule
A preposition combines with its object to form a preposition phrase. The preposition can put its object into the accusative or ablative case.
Rule 4: The adjective agreement rule
An adjective will have the same number, gender and case as the noun it describes.
Rule 5: The infinitive rule
Instead of or as well as an object, a verb case take an infinitive phrase.
