Can I learn Portuguese in one year with about 1 hour per day?

It is possible to gain a basic level of proficiency in Portuguese within one year of study if dedicating around 1 hour per day, but becoming truly fluent would take longer. Here are some factors to consider:

• With daily 1 hour study sessions, you can expect to complete a beginner Portuguese course within 6-9 months. This will build basic vocabulary and grammar foundations.
• At an hour a day, you’ll complete around 200-260 study hours in a year. This allows slow but steady progress through beginner and into intermediate levels.
• Be sure to supplement lessons with podcasts, music, TV/films to accelerate language acquisition through comprehensible input.
• Additional time spent practicing conversation is important since speaking takes the longest to develop. Language exchange apps/tutors help with this.
• It may take 1-2 years at 1 hour daily to reach an intermediate-mid level where you can discuss most everyday topics comfortably.
• Fluency generally requires 2-4 years of focused study to attain near-native mastery of vocabulary, idioms etc.
• Immersion through travel is highly beneficial for accelerating listening/speaking skills.

So while basic proficiency is plausible in 1 year at 1 hour daily, becoming truly fluent takes longer. But it provides a solid start and allows continual growth beyond the first year through consistent study, practice and immersion over time. Commitment is key to maximizing progress.
