Answer:
Will Latin help me learn other languages?
Latin is a great starting place, but not a definite one. It helps immensely, but each Romance language is still unique, and speakers of Spanish and Portuguese can still have a headache when trying not to speak "Portuñol". I.e., even native speakers can have a hard time learning other Romance languages.
