Questions & Answers about Dux necessitati cedit.
Dux is nominative singular. In this sentence, it is the subject because:
- it is the form a noun usually takes when it is doing the action
- the verb cedit is third person singular, so it matches a singular subject
- there is no other nominative noun present
Dux comes from dux, ducis and is a third-declension noun.
Because cedere commonly takes the dative of the person or thing one yields to.
So Latin says, literally, something like:
- the leader yields to necessity
not:
- the leader yields necessity
That is why the noun is necessitati rather than an accusative form such as necessitatem.
Because cedit here is not being used as a transitive verb with a direct object. Instead, cedere means to yield to, to give way to, or to submit to, and the thing yielded to is put in the dative.
So:
- necessitati = to necessity
- not a direct object, but a dative complement
