Questions & Answers about Rhodus insula clara est.
- Rhodus = the subject
- insula clara = the predicate noun + predicate adjective, describing what Rhodus is
- est = is, the linking verb
So the sentence has the pattern:
subject + predicate noun/adjective + linking verb
This is a very common Latin sentence type.
Because after a linking verb like est, Latin normally uses the nominative for both:
- the subject
- the predicate noun
So:
- Rhodus is nominative because it is the subject.
- insula is nominative because it tells us what Rhodus is.
This is similar to English Rhodes is an island, where both sides refer to the same thing.
