Hi, Dman
You are right, "to fight to the finish" is one of the possible translations of DECERTO, but take care that this word can be two different things:
- The way to enunciate the verb in Latin, equivalent to English "to ..."
- More properly, the first singular person of present: "I fight to the finish"
The choice depends on the concrete context.
The spelling in classical Latin is DEKERTO, with the accent on the second syllabe and the sound of both E as in THE.
Regards
