Audaciae is NOT an adjective.

I’d be grateful if someone could confirm the following is correct. Not sure why I had a difficulty, but initially I mistook audaciae for an adjective (audacious).

Fama audaciae nautas Britanniae ornat.
Fama (N sing) audaciae (G sing) nautas (Acc pl) Britanniae (G sing) ornat (verb).

The report of bravery adorns the sailors of Britain.

This is fine. Audacia is a noun, the adjectival form is audax, a third declension adjective.

Many thanks for your response. Onward and upward.
