Connecting and Relating

1. Contrast Patterns (けど/が)

Pattern: [Statement A]けど、[Statement B]

interface ContrastPattern {
  firstClause: {
    statement: BasicPattern;
    connector: けど | が;
  };
  secondClause: {
    statement: BasicPattern;
    context: "contrasting" | "unexpected";
  };
}

Examples:

• 日本語は難しいですけど、面白いです (Japanese is difficult, but interesting)
• お金がありますが、時間がありません (I have money, but I don’t have time)
• 漢字を勉強していますけど、まだ下手です (I’m studying kanji, but I’m still bad at it)

Validation Rules:

• First clause ends in plain/polite form
• けど/が attach directly to verb/adjective
• Second clause maintains politeness level

2. Reason/Cause (から/ので)

Pattern: [Reason]から/ので、[Result]

interface CausalPattern {
  reason: {
    statement: BasicPattern;
    connector: から | ので;
    formality: {
      から: "casual";
      ので: "formal";
    };
  };
  result: {
    statement: BasicPattern;
    context: "consequence";
  };
}

Examples:

• 忙しいから、行きません (Because I’m busy, I won’t go)
• 雨が降っているので、傘を持っていきます (Since it’s raining, I’ll take an umbrella)
• お腹が痛いので、病院に行きます (Because my stomach hurts, I’ll go to the hospital)

Validation Rules:

• から is more casual, ので more formal
• Reason must logically connect to result
• Maintains cause-effect relationship

3. Conditional Patterns (たら/と/ば/なら)

Pattern: [Condition]たら/と/ば/なら、[Result]

interface ConditionalPattern {
  condition: {
    statement: BasicPattern;
    transform: {
      たら: "completion";
      と: "natural result";
      ば: "general condition";
      なら: "given that";
    };
  };
  result: {
    statement: BasicPattern;
    context: "consequence";
  };
}

Examples:

• 雨が降ったら、行きません (If it rains, I won’t go)
• 春になると、桜が咲きます (When spring comes, the cherry blossoms bloom)
• お金があれば、買います (If I have money, I’ll buy it)
• 暇なら、映画を見ませんか (If you’re free, shall we watch a movie?)

Validation Rules:

• Condition form matches connector type
• Result must be logically consequent
• Temporal sequence must be valid

4. Purpose/Goal (ために/のに)

Pattern: [Goal]ために、[Action]

interface PurposePattern {
  goal: {
    statement: BasicPattern;
    connector: ために | のに;
    usage: {
      ために: "intentional purpose";
      のに: "expected purpose";
    };
  };
  action: {
    statement: BasicPattern;
    context: "means to achieve";
  };
}

Examples:

• 日本語を勉強するために、日本に行きます (I’ll go to Japan to study Japanese)
• 健康になるために、運動します (I exercise to become healthy)
• 試験に合格するために、毎日勉強します (I study every day to pass the exam)

Validation Rules:

• Goal must be achievable through action
• ために indicates intentional purpose
• Action must be volitional

5. Multiple Clause Combinations (て-form)

Pattern: [Action A]て、[Action B]て、[Action C]

interface MultiClausePattern {
  actions: Array<{
    statement: BasicPattern;
    connector: て | で;
    relationship: "sequence" | "cause" | "method";
  }>;
  finalState: {
    statement: BasicPattern;
    validation: です | します;
  };
}

Examples:

• 本を買って、家に帰って、読みます (I’ll buy a book, go home, and read it)
• お金を貯めて、車を買って、旅行します (I’ll save money, buy a car, and travel)
• 早く起きて、走って、会社に行きます (I wake up early, run, and go to work)

Validation Rules:

• て-form indicates continuation
• Final verb shows tense/politeness
• Actions must be logically sequential

Context Inheritance

Complex sentences maintain context through hierarchical relationships:

interface ContextInheritance {
  primaryContext: {
    topic?: Entity;
    time?: TimeExpression;
    location?: Place;
  };
  inheritanceRules: {
    explicit: "requires particle は";
    implicit: "continues from primary context";
    reset: "new は overrides previous";
  };
}

Example with Context Inheritance: 私は日本語が難しいですけど、毎日勉強しているので、だんだん上手になります (Although Japanese is difficult for me, because I study every day, I’m gradually improving)

Common Connection Errors

interface ConnectionError {
  logicalError: {
    wrong: "雨が降るから、晴れです";  // Logical contradiction
    correct: "雨が降るから、傘を持ちます";
  };
  formError: {
    wrong: "勉強だから、行きます";  // Wrong form before から
    correct: "勉強するから、行きます";
  };
  contextError: {
    wrong: "私は忙しいけど、友達は疲れてから、帰ります";  // Confused context
    correct: "私は忙しいけど、友達は疲れているから、帰ります";
  };
}

Pattern Integration Strategy

When combining multiple patterns, follow this hierarchy:

interface PatternIntegration {
  baseStructure: BasicPattern;
  modifications: {
    temporal?: TemporalPattern;
    conditional?: ConditionalPattern;
    causal?: CausalPattern;
  };
  connections: {
    primary: MainConnector;
    secondary?: SubConnector;
    final: EndState;
  };
}

Complex Integration Example: 雨が降っているので、図書館で勉強してから、友達と映画を見に行きたいですけど、時間がありません (Because it’s raining, I want to study at the library and then go watch a movie with my friend, but I don’t have time)
