Nouns As Subject
Nouns after the Preposition in
From these examples we learn that nouns change form to indicate how they function in a sentence. At this stage subjects end in -us or -a. When those same nouns occur after the preposition in, the endings change to -ō or -ā.
Subjects: -us, -a
After a Preposition: -ō, -ā
2. Verbs with a singular subject end in the letter -t, which indicates third person and singular. All verbs presented in this chapter are third person and singular.
sedet - bibit - dormit - lātrat - clāmat - est
1. The verb est, meaning is, does not take a direct object. Often it links its subject to another noun or adjective in the predicate.
via est longa.
hortus est magnus.
culīna est magna.
servus est coquus.
2. Latin frequently places the verb at the very end of a sentence.
canis in ātriō dormit.
servus in culīnā coquit.
pater in tablīnō sedet.
3. While subjects regularly come first, and verbs tend to be last, emphasis can be made by displacing a word from its common position. For example, placing a subject last can make it emphatic.
in culīnā coquit pater.
Father is cooking in the kitchen.
