Questions & Answers about Medica dicit dolorem in pectore non gravem esse.
Medica is the subject of the sentence, so it is in the nominative singular.
It is the feminine form, so it means female doctor (or woman doctor). If the doctor were male, you would expect medicus instead.
So:
- medica = nominative singular
- function = subject of dicit
This is one of the most important features of the sentence.
After a verb like dicit (says), Latin often uses indirect statement, also called the accusative-and-infinitive construction.
In a direct statement, you would have:
- dolor in pectore non gravis est = the pain in the chest is not serious
But after dicit, Latin changes that to indirect statement:
- dolorem in pectore non gravem esse
So:
- dolor → dolorem
- est → esse
That is why dolorem is accusative.
