Questions & Answers about Puer ad canem accedit et eum tangit.
Puer is the nominative singular form, which is the form Latin normally uses for the subject of the sentence.
Here, puer is the one doing the actions:
- accedit = he approaches
- tangit = he touches
So puer is nominative because the boy is the subject.
Because the preposition ad takes the accusative case.
So:
- canis = nominative, dog
- canem = accusative, dog as the object of motion toward something
With ad, Latin uses the accusative to show movement to, toward, or up to something:
- ad canem = to/toward the dog
So ad canem accedit means he approaches the dog or he goes up to the dog.
Accedit is from accedere, meaning to approach, to go to, or to come up to.
