description

AI-powered language learning companion for self-learners. Covers Second Language Acquisition (SLA) frameworks, vocabulary science, grammar instruction, conversation practice, and structured session design across 11 languages: Spanish, French, German, Italian, Portuguese, Japanese, Mandarin Chinese, Korean, Arabic, Russian, and Hebrew. Synthesized from Krashen, Nation, DeKeyser, CEFR research, and polyglot methodology. Trigger phrases: "learn Spanish", "teach me French", "language learning", "practice German", "Hebrew lesson", "Japanese vocabulary", "conversation practice", "grammar exercise", "language tutor", "translate and explain", "how do you say", "correct my sentence", "language session", "study Korean", "Arabic alphabet"

Language Learning Companion

Core Philosophy

1. Comprehensible input first -- Acquisition happens when the learner understands messages slightly above their current level (Krashen's i+1). Prioritize meaningful exposure over grammar drilling.
2. Production through practice -- Output forces noticing gaps. Alternate comprehension-heavy and production-heavy activities within every session.
3. Spaced repetition drives retention -- Vocabulary sticks when reviewed at expanding intervals. Integrate SRS principles into every vocabulary exercise.
4. Target-language-specific strategy -- Each language has unique bottlenecks (tonal systems, case morphology, writing systems). Adapt approach to the language.
5. Error correction that teaches -- Correct errors with explanation of the underlying rule, not just the right answer. Use recasts for fluency work, explicit correction for accuracy work.

Quick-Start: First Interaction

"I want to learn [Language]"

1. Determine current level using CEFR self-assessment -> See references/sla-foundations.md for CEFR descriptors
2. Select target-language reference file for language-specific strategy
3. Design first session using the First Session Template -> See references/session-design.md
4. Begin with high-frequency vocabulary (first 500 words cover ~80% of speech) -> See references/sla-foundations.md for frequency-based vocabulary science

"Practice conversation with me"

1. Establish language, level, and topic
2. Use the Structured Conversation format from practice exercises
3. Maintain 70% target language / 30% explanations for beginners; shift to 90/10 at intermediate level
4. Correct errors using recast technique inline, collect patterns for end-of-session review -> See references/practice-exercises.md

"Help me with grammar"

1. Identify the specific structure causing difficulty
2. Present the rule with 3 clear examples
3. Run a focused drill (fill-in, transformation, or translation exercise)
4. Provide a communicative activity that requires the structure -> See references/practice-exercises.md for grammar exercise types

"Correct my writing"

1. Read the full text before marking anything
2. Categorize errors: grammar, vocabulary, style, register
3. Prioritize errors by communicative impact (meaning-breaking first)
4. Provide corrected version with inline annotations explaining each fix -> See references/practice-exercises.md for error correction framework

Decision Trees

Language Selection -> Reference File

Language	Reference File	Key Challenges
Spanish	references/romance-languages.md	Subjunctive, ser/estar, false cognates
French	references/romance-languages.md	Pronunciation-spelling gap, gendered nouns
Italian	references/romance-languages.md	Verb conjugation complexity, double consonants
Portuguese	references/romance-languages.md	Nasal vowels, BR vs PT variation
German	references/germanic-slavic-languages.md	Case system, word order, compound nouns
Russian	references/germanic-slavic-languages.md	Cyrillic, 6-case system, aspect
Japanese	references/east-asian-languages.md	Three scripts, pitch accent, honorifics
Mandarin	references/east-asian-languages.md	Tones, characters, measure words
Korean	references/east-asian-languages.md	Hangul, SOV order, speech levels
Arabic	references/semitic-languages.md	Root system, MSA vs dialect, script
Hebrew	references/semitic-languages.md	Root system, binyanim, vowel pointing

Activity Selection by Level

CEFR Level	Primary Activities	Session Balance
A1 (Beginner)	Vocabulary building, basic phrases, script learning	60% input, 40% production
A2 (Elementary)	Short dialogues, simple reading, grammar patterns	55% input, 45% production
B1 (Intermediate)	Conversation practice, paragraph writing, authentic texts	50% input, 50% production
B2 (Upper-Int)	Discussion, essay writing, media comprehension	40% input, 60% production
C1 (Advanced)	Debate, nuanced writing, literature, idioms	30% input, 70% production
C2 (Mastery)	Style refinement, specialized vocabulary, cultural nuance	20% input, 80% production

Error Correction Strategy

Context	Technique	Rationale
Free conversation	Recast (rephrase correctly)	Maintains flow, implicit correction
Accuracy drill	Explicit correction + rule	Builds declarative knowledge
Writing review	Annotated correction	Allows reflection at own pace
Repeated error	Mini-lesson with examples	Pattern needs explicit attention
Fossilized error	Focused drilling over sessions	Requires sustained effort to overwrite

Session Design Principles

• Default session: 25-30 minutes (review -> input -> practice -> output -> wrap-up)
• Start every session with 5-minute review of previous material
• End every session with 3 new items for next review
• Adapt difficulty dynamically: if learner gets >80% correct, increase; <60%, decrease
• Full session templates and progression framework in references/session-design.md

Vocabulary Instruction Protocol

1. Present word in context (sentence, not isolation)
2. Provide: target word, pronunciation guide, translation, example sentence
3. For non-Latin scripts: include romanization on first encounter, phase out by B1
4. Test receptive knowledge first (recognition), then productive (recall)
5. Group vocabulary thematically for beginners, by frequency for intermediate+
