Adds an explanatory or contextualizing tone to a statement. In speech, often contracts to んです (informal) or のです (formal). Used when providing a reason, clarification, or background information — not for simple factual statements. Also used in questions (〜んですか) to signal that the speaker is seeking an explanation, not just a yes/no answer. Without のです, a sentence like お腹が痛い is a bare report; with んです (お腹が痛いんです), it conveys 'the situation is that my stomach hurts' — inviting empathy or follow-up.

A closed set of verbs that inherently express respect toward the subject. They replace the plain verb entirely — not a suffix you add. Key verbs: いる・行く・来る → いらっしゃる, 言う → おっしゃる, 食べる・飲む → 召し上がる, 見る → ご覧になる, する → なさる, 知っている → ご存じだ, くれる → くださる. These are the most natural and common way to express respect in daily Japanese. The ます form of いらっしゃる is いらっしゃいます (not いらっしゃります), and くださる becomes くださいます. Used for the actions of superiors, customers, teachers — anyone to whom the speaker wishes to show respect.

A productive honorific pattern for verbs that don't have a dedicated honorific verb. The structure is お + masu-stem + になる (e.g., 読む → お読みになる). If the verb already has a special honorific form (e.g., 言う → おっしゃる), prefer the special form. Avoid using this for very short verbs like 見る (use ご覧になる), する (use なさる), and いる (use いらっしゃる). Also avoid for verbs with only one mora before ます (e.g., 寝る → お寝になる is awkward; use お休みになる instead). The pattern raises the subject's action to a respectful level — equivalent to V-(ら)れます in meaning, but slightly more formal.

Uses the same form as the passive but functions as an honorific — the subject is respected, not acted upon. This is a relatively light, natural form of respect used widely in daily conversation and public announcements (e.g., train announcements: まもなく電車が参ります → speaker humbling self; but お客様が乗られます → respecting the customer via passive-honorific). Less formal than お〜になる but perfectly polite. Context distinguishes honorific from passive: if the subject is someone you respect and the verb is their action, it's honorific. Can also combine with お〜になる for double honorific (overly polite and rare). Group 1 verbs sometimes contract: 行かれる, 話される, 立たれる.

A polite request pattern directed upward — used when asking a superior, customer, or stranger to do something. The structure is お + masu-stem + ください. For verbs that use ご prefix (Sino-Japanese), the form is ご + VN-stem + ください (e.g., 注意 → ご注意ください). More polite than 〜てください and more direct than 〜ていただけませんか. Common in public signage, announcements, and service encounters. Note: some verbs have irregular forms — くれる → ください (not おくれください), する → なさってください is preferred over おしください.

A closed set of verbs that lower the speaker's (or in-group's) action relative to the listener or a third party. Key humble verbs: 行く・来る → 参る (まいる), 言う → 申す (もうす), する → いたす, いる → おる, 知っている → 存じている (ぞんじている), 食べる・飲む → いただく, もらう → いただく, あげる → 差し上げる (さしあげる), 見る → 拝見する (はいけんする), 聞く → 伺う (うかがう), 会う → お目にかかる (おめにかかる). Humble verbs describe the speaker's or in-group's actions directed toward a respected person. Never use humble verbs for the respected person's own actions — that would be rude. Note the difference between 参る (humble, lowering self) and いらっしゃる (honorific, raising the other).

A productive humble pattern for verbs that don't have a dedicated humble verb. The speaker lowers their own action, which indirectly elevates the listener or a respected third party. いたします is the humble form of する, so お〜いたします is more polite than お〜します. If the verb already has a special humble form (e.g., 言う → 申す, 見る → 拝見する), prefer the special form. The pattern implies the action is for the listener's benefit — お持ちします means 'I'll carry it FOR YOU,' not just 'I'll carry it.' Sino-Japanese verbs use ご prefix instead of お: ご案内します, ご連絡いたします.

The ultra-polite form of ある (there is) and です (it is). ございます is the humble-polite form of ある, used to state existence of objects politely (not people — for people use いらっしゃいます). でございます is the ultra-polite copula replacing です. Combined with adjectives, it produces fossilized polite expressions: ありがたい → ありがとうございます, 早い → おはようございます, めでたい → おめでとうございます. The adjective + ございます pattern follows a euphonic sound shift: the last -i syllable of the adjective shifts to the -ou row (e.g., 高うございます for 高い, 広うございます for 広い). This pattern is increasingly rare in modern speech outside of set phrases and very formal business contexts.

The honorific prefixes お and ご attach to nouns (and sometimes adjectives) to show respect toward the person the thing belongs to or is associated with. General rule: お + native-Japanese words (和語) — お名前, お金, お茶, お天気; ご + Sino-Japanese words (漢語) — ご連絡, ご家族, ご意見, ご住所. Exceptions exist (e.g., お電話 uses お despite being Sino-Japanese — it's so common it naturalized; お料理, お掃除 are hybrid). Not every noun takes these prefixes — overusing them sounds like hyper-polite 'beautification' speech (美化語). If unsure, it's safer to omit. Some words are rarely used without the prefix (お茶 is the normal word for tea; 茶 alone sounds rough).

A concise honorific pattern used to describe someone else's current action or resulting state. The structure is お + masu-stem + です (e.g., 待つ → お待ちです = 'is waiting'). Functions like a polite stative observation — more concise than お待ちになっています but equally respectful. Common in service situations: お客様、お待ちです = 'Sir/Madam, your party is waiting (for you).' Can describe both ongoing actions and resulting states: お帰りです can mean 'is going home' or 'has gone home' depending on context. For Sino-Japanese verbs, use ご instead of お: ご到着です, ご出発です. Not used for the speaker's own actions.

Marks the role, capacity, or identity under which the subject acts or is evaluated. The noun marked by として is the role the subject assumes — not the evaluator. The predicate is typically an action the subject performs IN that role, or a statement ABOUT the subject in that capacity. として can also mark abstract standards: 趣味として 'as a hobby,' 原則として 'as a general rule,' 結果として 'as a result.' Also used with は for contrast (〜としては) to mean 'as for (that role), at least.' Contrast with にとって: 私にとって大切だ = 'It is important to me' (I judge); 私として意見を言う = 'I speak as myself / in my capacity' (I assume the role of expressing my view).

Marks the entity from whose perspective a judgment or evaluation is made. The noun marked by にとって is the evaluator — the one who feels, judges, or values something. The predicate is typically an evaluative adjective (大切, 重要, 難しい, 必要) or a judgment statement. にとって cannot be used when the predicate is a concrete benefit or action — for that use には (e.g., 私には兄弟がいる 'I have siblings,' NOT 私にとって兄弟がいる). The pattern frames the judgment as relative to the evaluator's standpoint: different people may judge differently. Contrast with として: にとって marks the judge, として marks the role the subject assumes.

Marks an abstract dimension or framework within which a statement is evaluated — 'in terms of X,' 'from an X standpoint.' Different from 〜の上で meaning 'after doing X' (V-た + 上で). The pattern N + 上 often follows Sino-Japanese words directly without の: 計算上 (calculation-wise), 理論上 (theoretically), 教育上 (educationally), 形式上 (formally). With の, it's more concrete: 法律の上では (in the eyes of the law). The は in 〜の上では makes it contrastive — the statement may not hold outside that framework. 上の functions as a prenominal modifier: 計算上の誤差 (a calculational error / an error in terms of calculation).

Expresses that something is disproportionate relative to a standard. The pattern is: 'Considering X, Y is unexpectedly (adjective).' X sets an expectation, and Y says the reality departs from it — often in a counter-expectation direction. Typical use: 値段のわりに美味しい (delicious considering the price — i.e., cheap but good) or 高いわりにまずい (bad despite being expensive). The mismatch can be positive or negative. The は in わりには is optional and adds a contrastive nuance. Common with adjectives of quality, size, and degree. Distinct from にしては: わりに focuses on the proportionality judgment (X and Y don't match); にしては focuses on the surprise given a specific attribute X (For an X, it's surprisingly Y).

Expresses that a result is surprising or unexpected given the subject's stated attribute. The structure is: 'X にしては Y' — 'For an X, it is Y' (and Y goes against what X would normally imply). The attribute X sets up a norm, and Y says the reality deviates from that norm. Often used for people: 外国人にしては日本語が上手 (For a foreigner, your Japanese is good — it's surprisingly good). The judgment is anchored to a specific attribute, making it more targeted than わりに. Can express positive or negative surprise. Contrast with だけあって: にしては defies an expectation based on X; だけあって confirms that the expectation based on X is met.

Marks a noun as the framework or standpoint from which a judgment is made. The variants are interchangeable in most contexts: からいうと (most common, 'speaking from'), からいえば (conditional, 'if one judges from'), からいって (continuative, 'judging from, ...'). The noun is typically an abstract criterion: 経験, 立場, 性格, 実績, 常識, ルール. The judgment is the speaker's reasoned conclusion — not a deduction from direct evidence (contrast with からすると, which is more evidence-based). Also note that からいうと often sounds more like 'speaking from the perspective of X as a framework,' whereas からすると sounds more like 'based on the concrete data of X.' In practice, they are often interchangeable for abstract nouns.

Marks a noun as the evidence or data point from which an inference is drawn. Variants: からすると (most common, 'judging from'), からすれば (conditional, 'if one judges from'), からして (emphatic — 'even just from X, one can tell'). からして is particularly distinctive: it means 'even judging from X alone (without needing more evidence), one can already conclude Y.' This makes からして useful for strong first-impression judgments. The noun is often a concrete, observable thing: 様子, 表情, 口調, 服装, データ. Contrast with からいうと: からすると leans toward inference from evidence; からいうと leans toward judgment from a framework. However, the two are often interchangeable in practice with many nouns taking either pattern naturally.

Asks the listener to imagine standing in someone else's shoes — to see things from that person's perspective. The noun is typically a person or group whose viewpoint the speaker wants the listener to consider empathetically. にしたら and にすれば are nearly identical; にすれば has a slightly conditional feel ('if you were to take X's position'). Often used when the speaker is defending or explaining someone's otherwise puzzling behavior — 'Look, from his point of view, it makes sense.' Distinct from にとって: にとって states a general evaluative standpoint; にしたら invites empathetic imagination of a specific person's feelings in a specific situation. Contrast with にしたところで (even from X's standpoint, Y is still the case — concessive, not empathetic).

Expresses that someone does something to the best of their ability within their own limits or at a level appropriate to their situation. Often repeated with the same noun: 子供は子供なりに (children, in their own childlike way), 私なりに (in my own way). Implies acceptance of imperfection — not claiming the result is great, but it's the best one can do at that level. なりの modifies nouns: 子供なりの悩み (worries that are real for a child, even if they seem trivial to adults). The pattern has a gentle, non-judgmental tone — validating effort at any level. Distinct from わりに: なりに is about doing things within one's own frame (self-referential); わりに is about things being disproportionate to an external standard (comparative).

Expresses that the result naturally matches the high expectation set by the subject's reputation, status, or nature. The structure is: 'X だけあって Y' — 'Being the X that it/he/she is, it's only natural that Y.' Y is always a positive or affirming statement that confirms the expectation. Often paired with さすが (as expected) for reinforcement: さすが〜だけあって. The pattern always implies admiration or recognition — it acknowledges that a reputation is deserved. Contrast with にしては: だけあって confirms expectations (名店だけあって美味しい = it's good BECAUSE it's a famous shop); にしては defies them (高いにしてはまずい = it's bad DESPITE being expensive).

Marks a noun that represents an elevated or special status, stage, or time — once that threshold is reached, things change qualitatively. The noun is typically something that brings higher expectations or different conditions: 社長 (company president), 春 (spring), プロ (professional), 結婚 (marriage), 大学生 (college student). The predicate describes the natural consequence of reaching that level — often about new responsibilities, new environments, or seasonal changes. ともなると and ともなれば are largely interchangeable; ともなれば has a slightly more conditional flavor ('if/when it reaches the point of'). Often implies a societal or natural shift, not just a personal one. Distinct from simple 〜たら or 〜ば: those mark simple conditions; ともなると marks a threshold that triggers a paradigm shift.

A concessive pattern meaning 'even taking X's standpoint, the situation doesn't change' or 'not even X can do Y.' Unlike にしたら (which invites empathy), にしたところで acknowledges a perspective only to dismiss or limit it. The structure is: even the most authoritative / advantageous standpoint X doesn't change the bottom line Y. Often used with a negative or limiting predicate: 〜とは限らない (not necessarily), 〜わけではない (doesn't mean that), 〜できない (cannot). にしたところで is slightly more formal than としたところで, but both are N1-level formal. The nuance is close to 'Granted, even X...' or 'Even X, for that matter,...'

A N1-level pattern expressing strong condemnation that someone of a certain respected standing or social role would do something unbefitting. The noun is a position or role that implies high moral or professional standards: 教師 (teacher), 医者 (doctor), 政治家 (politician), 親 (parent). The pattern is always followed by ものが, 人物が, or 人間が (person/human being) to refer to the person in that role. 〜なんて / 〜とは at the end reinforces the incredulous or outraged tone. The speaker is not just disappointed but morally shocked: someone entrusted with a position of responsibility has violated the trust inherent in that role. Never used for trivial matters — reserved for serious breaches of duty or ethics.
