Decide Whether to Learn a Language Formally or by Immersion

The app is gamified and rewarding and produces beginners. Living somewhere forces fluency but requires a base to build on. This compares formal study and immersion for your proficiency target and timeline, explains why the right answer depends on where you are starting from, and recommends the hybrid approach that is most likely to work.

<context>
Someone wants to reach {PROFICIENCY_TARGET} (e.g. conversational, business fluent, basic travel) in {LANGUAGE} within {TIMEFRAME}. Their current level is {CURRENT_LEVEL} and their immersion access is {IMMERSION_ACCESS} (e.g. none, occasional native speakers, living in the country, media available).
</context>

<task>
Compare formal study versus immersion across:
1. Rate of progress for the proficiency target and timeframe stated
2. Which works for the current level (immersion tends to fail at zero or near-zero base)
3. Error acquisition: the specific type of errors each method tends to produce that the other prevents
4. The pragmatic hybrid most likely to hit the stated target in the stated time
5. Recommendation with the one assumption it depends on
