7.1 Honorific (Sonkeigo) & Humble (Kenjougo) Foundations: Three Branches, Regular Patterns, Irregulars & Uchi/Soto Rules

Honorific (Sonkeigo) & Humble (Kenjougo) Foundations: Three Branches, Regular Patterns, Irregulars & Uchi/Soto Rules

Core Principle: Japanese honorific speech (敬語 - Keigo) is not merely an optional layer of polite vocabulary; it is a systematic grammatical mechanism that modulates social distance, hierarchy, and respect between speakers, listeners, and third parties. On the JLPT N4, keigo questions test your ability to determine who is performing the action (the subject) and who is receiving the benefit or respect, matching the correct honorific (尊敬語 - Sonkeigo) or humble (謙譲語 - Kenjougo) verb forms accordingly.

Keigo appears extensively across Grammar Mondai 1 (Form Selection), Grammar Mondai 2 (Sentence Composition ★), Reading Comprehension (Dokkai notices and emails), and Listening Mondai 3 & 4 (Verbal Expressions and Quick Response). Mastering keigo requires fluency in three interconnected systems: the three grammatical branches, regular vs. irregular verb conjugations, and the sociolinguistic Uchi/Soto boundary.

1. The Three Branches of Japanese Keigo

Japanese politeness operates across three distinct grammatical registers, each serving a unique pragmatic function:

THE THREE BRANCHES OF KEIGO
┌──────────────────┬─────────────────────────────────┬─────────────────────────────────┐
│ Branch           │ Grammatical Target & Direction  │ Primary Pragmatic Purpose       │
├──────────────────┼─────────────────────────────────┼─────────────────────────────────┤
│ 1. 丁寧語         │ Speaker ──→ Listener            │ Expresses general politeness    │
│    (Teineigo)    │ (Neutral baseline politeness)   │ and social distance (です/ます). │
├──────────────────┼─────────────────────────────────┼─────────────────────────────────┤
│ 2. 尊敬語         │ Speaker ──↑ Out-Group Subject   │ Elevates the status of the      │
│    (Sonkeigo)    │ (Upward: Subject is superior)   │ subject (teacher, boss, client).│
├──────────────────┼─────────────────────────────────┼─────────────────────────────────┤
│ 3. 謙譲語         │ Speaker ──↓ In-Group Subject    │ Lowers the speaker's own action │
│    (Kenjougo)    │ (Downward: Subject is self/uchi)│ to show respect to the recipient│
└──────────────────┴─────────────────────────────────┴─────────────────────────────────┘

A. Teineigo (丁寧語 - Polite Language)

Teineigo is the neutral polite baseline taught in beginner Japanese. It uses the copula です (desu) and verb suffix 〜ます (-masu) to show general courtesy toward the conversation partner regardless of who performs the action. It does not grammatically elevate or lower specific individuals.

• 私は明日東京へ行きます。(I am going to Tokyo tomorrow.)
• 田中さんは先生です。(Tanaka is a teacher.)

B. Sonkeigo (尊敬語 - Honorific Language)

Sonkeigo is used when describing the actions, states, possessions, or family members of a respected person (a teacher, a customer, a company superior, or an external partner). By using Sonkeigo, the speaker elevates the subject of the sentence.

• Golden Rule of Sonkeigo: NEVER use Sonkeigo to describe your own actions or the actions of your in-group family/company members.
• 先生はもう本をお読みになりました。(The teacher has already read the book. → Subject is teacher; elevated).
• 社長がおっしゃいました。(The company president said... → Subject is president; elevated).

C. Kenjougo (謙譲語 - Humble Language)

Kenjougo is used when describing the actions of the speaker or the speaker's in-group (family members, company colleagues) performed towards or for the benefit of a respected person. By using Kenjougo, the speaker humbles their own action, which indirectly elevates the recipient of the action.

• Golden Rule of Kenjougo: NEVER use Kenjougo to describe the actions of a teacher, customer, or superior.
• 私が荷物をお持ちします。(I will carry your luggage. → Subject is speaker; humbled).
• 明日、社長にスケジュールをご報告いたします。(I will report the schedule to the president tomorrow. → Subject is speaker; humbled).

2. Regular Honorific & Humble Formulas

When a verb does not possess a specialized irregular form, it is converted into Sonkeigo or Kenjougo using standard morphological formulas based on whether the word is native Japanese (和語 - Wago) or Sino-Japanese (漢語 - Kango).

REGULAR KEIGO DERIVATION FORMULAS
┌────────────────────────┬─────────────────────────────────────────────────────────────┐
│ Category               │ Morphological Formula                                       │
├────────────────────────┼─────────────────────────────────────────────────────────────┤
│ Sonkeigo (Honorific)   │ 和語: お + Verb Masu-Stem + になる                          │
│                        │ 漢語: ご + Sino-Japanese Noun + になる / なさる             │
│                        │ 依頼: お + Verb Masu-Stem + ください                        │
├────────────────────────┼─────────────────────────────────────────────────────────────┤
│ Kenjougo (Humble)      │ 和語: お + Verb Masu-Stem + する / いたす                    │
│                        │ 漢語: ご + Sino-Japanese Noun + する / いたす                │
└────────────────────────┴─────────────────────────────────────────────────────────────┘

A. Regular Sonkeigo Patterns (尊敬語)

1. Native Verbs: お + Verb Masu-Stem + になる

• 帰る → お帰りになる (To return home / go back)
  • 部長はもうお帰りになりました。(The department manager has already gone home.)
• 待つ → お待ちになる (To wait)
  • 社長がロビーでお待ちになっています。(The president is waiting in the lobby.)
• 読む → お読みになる (To read)
  • この本をもうお読みになりましたか。(Have you already read this book?)
• 使う → お使いになる (To use)
  • どちらのペンをお使いになりますか。(Which pen will you use?)

2. Sino-Japanese Verbal Nouns: ご + Noun + になる / なさる

• 連絡する → ご連絡になる / ご連絡なさる (To contact)
  • 先生が後でご連絡になります。(The professor will contact us later.)
• 利用する → ご利用になる (To use / make use of)
  • エレベーターをご利用になりますか。(Will you be using the elevator?)
• 参加する → ご参加なさる / ご参加になる (To participate)
  • 明日のパーティーにご参加なさいますか。(Will you participate in tomorrow's party?)

3. Honorific Requests: お/ご + Stem + ください

• お入りください (Please come in)
• お座りください (Please have a seat)
• 少々お待ちください (Please wait a moment)
• ご注意ください (Please be careful / watch out)
• ご確認ください (Please confirm / check)

Morphological Exception Alert: Verbs with a single-mora masu-stem (e.g., 見る → 見, 寝る → 寝, 着る → 着, いる → い) CANNOT take the regular お+Stem+になる pattern (*お見になる is ungrammatical). These verbs rely strictly on irregular keigo forms (ご覧になる for 見る, お休みになる for 寝る).

---

B. Regular Kenjougo Patterns (謙譲語)

1. Native Verbs: お + Verb Masu-Stem + する / いたす

Attaching いたす (the humble counterpart of する) creates a higher degree of formal humility.

• 待つ → お待ちする / お待ちいたします (I will wait for you)
  • 駅の改札口でお待ちいたします。(I will wait for you at the station ticket gate.)
• 持つ → お持ちする / お持ちいたします (I will hold/carry for you)
  • その重い荷物をお持ちしましょうか。(Shall I carry that heavy luggage for you?)
• 貸す → お貸しする (I will lend to you)
  • 私の傘をお貸しします。(I will lend you my umbrella.)
• 手伝う → お手伝いする / お手伝いいたします (I will assist you)
  • 部長のお仕事をお手伝いいたします。(I will assist with your work, Director.)

2. Sino-Japanese Verbal Nouns: ご + Noun + する / いたす

• 案内する → ご案内する / ご案内いたします (I will guide you)
  • 会議室へご案内いたします。(I will guide you to the conference room.)
• 説明する → ご説明する / ご説明いたします (I will explain to you)
  • 本日の予定をご説明いたします。(I will explain today's schedule.)
• 連絡する → ご連絡する / ご連絡いたします (I will contact you)
  • 明日の朝、メールでご連絡いたします。(I will contact you by email tomorrow morning.)
• 招待する → ご招待する (I will invite you)
  • 私の結婚式に先生をご招待したいです。(I would like to invite you, Professor, to my wedding.)

3. Master Irregular Keigo Verb Table (High-Yield N4 Core)

The vast majority of JLPT N4 keigo questions target irregular honorific and humble verbs. These forms completely replace the base verb stem and must be memorized with 100% precision.

Irregular Conjugation Peculiarities on Test Day

Four irregular Sonkeigo verbs do not conjugate their masu-form with the standard -ri- stem; instead, the -ri- drops to -i-:

• いらっしゃる → いらっしゃいます (NOT いらっしゃります)
• おっしゃる → おっしゃいます (NOT おっしゃります)
• なさる → なさいます (NOT なさります)
• くださる → くださいます (NOT くださります)

4. The Uchi vs. Soto Framework & Workplace Telephone Protocols

In Japanese pragmatics, keigo choice is determined not by absolute social rank, but by relative social grouping: the distinction between Uchi (内 - In-Group) and Soto (外 - Out-Group).

THE UCHI VS. SOTO WORKPLACE MATRIX

  [Inside Your Company: UCHI]                  [Outside World: SOTO]
┌──────────────────────────────┐              ┌──────────────────────────────┐
│ Talking to Company President │              │ Talking to an External Client│
│ (President is Superior / SOTO│              │ (Client is SOTO; Entire      │
│  relative to you internally) │              │  Company is UCHI)            │
│                              │              │                              │
│ • Use SONKEIGO for President:│              │ • Use KENJOUGO for President:│
│   「社長、書類をご覧になりまし│              │   「社長の田中は外出して     │
│    たか。」                  │              │    おります。」              │
│                              │              │ • STRIP TITLE: "田中" (not 田中社長)│
└──────────────────────────────┘              └──────────────────────────────┘

A. The Core In-Group Principle

When interacting with an external person (client, guest, customer), all members of your own company become Uchi (in-group). Even if you are talking about your company president or CEO, you must:

1. Drop all honorific titles and suffixes: Refer to your president simply by their family name (e.g., "田中", never "田中社長" or "田中さん").
2. Use Kenjougo (Humble speech) to describe their actions: Treat their actions as part of your humble in-group.

B. Business Telephone Dialogue Example (High-Frequency Listening Scenario)

• Client (Soto): 「ABC商事の佐藤と申しますが、山田部長はいらっしゃいますか。」("This is Sato from ABC Corp. Is Department Manager Yamada in?")
• You (Uchi Secretary): 「あいにく山田はただいま席を外しております。1時間ほどで戻る予定でございます。」("Unfortunately, Yamada is currently away from his desk. He is scheduled to return in about an hour.")
• Client (Soto): 「では、また後でお電話いたします。」("In that case, I will call again later.")
• You (Uchi Secretary): 「かしこまりました。山田に申し伝えます。」("Understood. I will pass the message along to Yamada.")
