Teineigo (丁寧語): Japanese Polite Language with です, ます, and ございます
Teineigo is Japanese polite language. It is the register marked by the sentence-ending copula です and the verb ending ます.1 Because most learners study it first, it becomes the baseline that every other layer of keigo builds on.2
Overview
Teineigo (丁寧語) is the part of keigo (敬語, honorific language) that makes a sentence more polite toward the person you are speaking to. Its two hallmark markers are です on nouns and na-adjectives, and ます on verbs.1
The polite layer is not a single flat level. It has an everyday default tier (です / ます) and an elevated formal tier (でございます / ございます) that sits above it on the same scale.13
Teineigo within the keigo system
Keigo splits into three kinds. Teineigo is an addressee honorific, directed at the person being talked to. Sonkeigo (respect) and kenjogo (humility) are referent honorifics, directed at the person being talked about.1
That distinction is the heart of teineigo. The ます suffix "expresses politeness toward and distance from the listener." In simpler terms, teineigo is listener-directed rather than subject-directed.4
The full sonkeigo and kenjogo system, including the regular honorific and humble verb patterns, belongs in the keigo hub article rather than here.
The two tiers of the polite layer
For the same basic meaning, the polite layer offers steps on a single politeness ladder. Standard reference grammar lines them up against the plain form like this:1
| Tier | Form | Example |
|---|---|---|
| Plain | だ | これは本だ |
| Polite (default) | です | これは本です |
| Very polite / formal | でございます | これは本でございます |
The everyday default is です / ます. The elevated tier is でございます / ございます. The elevated copula でございます "in principle can be used anywhere です is used," but in actual use it sounds very formal or stilted.3
これは本です。1
"This is a book."
これは本でございます。1
"This is a book." (elevated, formal register)
Form and rules
The polite copula です
です is the polite form of だ (da), the copula meaning "to be."5 It attaches after nouns and na-adjectives, in the same slot that the plain copula だ fills.6
Grammatically, です is "phonologically an enclitic, similar to particles." It is classified as a 助動詞 (jodōshi, "auxiliary verb").5
The polite copula inflects for tense and polarity:7
| Form | Marker | Example with 本 (book) |
|---|---|---|
| Present | です | 本です |
| Past | でした | 本でした |
| Present negative | ではありません | 本ではありません |
| Past negative | ではありませんでした | 本ではありませんでした |
これは私のパソコンです。5
"This is my PC."
昨日はいい天気でした。5
"It was good weather yesterday."
The plain copula だ is the contrasting form. When casual speech ends a sentence in だ, the polite register swaps in です with no other change to the noun or adjective.6
彼は無実だ。6
"He is innocent." (plain form; the polite form would be 無実です)
A question simply adds the particle か after です.
このパスポートはあなたのですか。5
"Is this passport yours?"
The verb ending ます
ます is the polite verb auxiliary. Like です, it "expresses politeness toward and distance from the listener." It is classified as an auxiliary verb (助動詞).4
ます attaches to the ren'yōkei (連用形, the "continuative" or stem form) of a verb. It then inflects partially like a godan verb.4 Reference grammar gives the formation as "continuative + masu":8
| Verb | Stem (連用形) | Polite form |
|---|---|---|
| 書く (write) | 書き | 書きます |
| 見る (see) | 見 | 見ます |
| 食べる (eat) | 食べ | 食べます |
The auxiliary itself conjugates for tense and polarity: present ます, past ました, present negative ません, and past negative ませんでした.48
今日は、寿司を食べに銀座に行きます。9
"I'll go to Ginza today to eat sushi."
食べます。9
"I (will) eat." (polite form of 食べる)
行きます。10
"I (will) go." (polite non-past of 行く)
Because ます marks politeness toward and distance from the listener, it is the safe default verb ending for any out-of-group exchange. It does not elevate the subject.4
The full ます paradigm and the verb-stem patterns it attaches to have their own dedicated articles. This section is only a preview.
The elevated tier: でございます and ございます
ございます is the "formal polite form of ある (aru): to exist."11 It comes from a sound change in 御座ります (gozarimasu, the polite form of "to exist").11
でございます is the "formal polite form of である (de aru)," built from で (the continuative form of だ) plus ございます.3 It is the elevated copula, one rung above です on the same ladder.17
A key property is that でございます is "neutral to who the subject is."7 It raises politeness toward the listener without lifting the status of anyone in the sentence.
ございます also attaches to the adverbial form of certain adjectives to build elevated set expressions. That is why several everyday greetings end in it.111213
おあつらえ向きのお品がございます。11
"We have items that are suitable for you." (service register)
ありがとうございました。11
"Thank you."
でございます can in principle go anywhere です goes, but in ordinary use it "sounds very formal or stilted."3 Keep it for service speech, announcements, and formal address. In casual conversation, it reads as stiff.
In everyday Japanese, ございます survives mainly in fixed inflected forms such as ございました, ございましたら, and ございます. It also survives inside です, which "may originate from a contraction of でございます."145
The で-form polite alternations
The same copula climbs a single politeness ladder by swapping its ending. The shared element is で: でございます is で (the continuative form of だ) plus ございます. です is widely analyzed as a worn-down でございます.53 The whole scale attaches to the same noun or na-adjective predicate.637
The cleanest way to see it is one predicate moving up the scale:1
これは本だ。1
"This is a book." (plain)
これは本です。1
"This is a book." (polite default)
これは本でございます。1
"This is a book." (elevated formal)
All three forms have the same basic truth meaning. Only the listener-directed politeness level changes as you move up the ladder.1
Nuance and usage contexts
Default polite: when です/ます is enough
です / ます is the standard polite form and the baseline taught first. Broadcast presenters use it "invariably."12
Because it is an addressee honorific and neutral to the subject, です / ます is the safe register for strangers, teachers, and colleagues in ordinary out-of-group interaction. It avoids both over-elevating and under-elevating the subject.14
The ます ending already encodes "politeness toward and distance from the listener," so the default tier signals appropriate social distance without the stiffness of the elevated tier.4
Elevated polite: when ございます/でございます fits
The elevated tier is reserved for high-formality contexts; outside them it "sounds very formal or stilted."3
Its native habitat is customer-facing service speech. ございます appears in shop speech, and いらっしゃいませ is "used by a store person to greet a customer."1115
おあつらえ向きのお品がございます。11
"We have items that are suitable for you." (service register)
Announcements, formal speeches, and business reception use this tier for the same reason: it raises politeness toward the audience without elevating any particular subject.37
Even いらっしゃいませ is built on ませ, the imperative of ます. This shows that the elevated service register is the same teineigo machinery pushed to its formal extreme.15
Teineigo is independent of subject elevation
でございます is "neutral to who the subject is," so it pairs with both respectful (sonkeigo) and humble (kenjogo) speech.7
This neutrality is exactly why teineigo is the base layer under the other two. It adjusts politeness toward the listener (an addressee honorific) rather than the status of the subject (a referent honorific).17
Because the polite layer encodes only listener-directed politeness, a single sentence can carry teineigo plus sonkeigo or kenjogo at the same time. The keigo hub article covers how those layers combine.
Good to know
です is a worn-down でございます
です "may derive from でございます (de gozaimasu), from で plus ございます." An alternative theory derives it from であります.5 Either way, the elevated form is the fuller ancestor and です is the contracted descendant.
ございます is itself the ます-form descendant of classical ござる, "the polite form of 有る (aru)." In modern Japanese, ござる survives only in a few inflected forms: ございました, ございましたら, ございます, and です.14
Read in order, the chain is で + ござ(る) + ます → でございます → worn down to です. That history is why the elevated form feels like a fuller, more complete version of the everyday です.514
Why ありがとうございます and おはようございます end in ございます
These greetings are an adjective in adverbial form plus ございます, which makes them teineigo in disguise.
ありがとう comes from ありがたく, the adverbial form of ありがたし (modern ありがたい, "grateful"), through the phonetic shift /aɾiɡataku/ → /aɾiɡatau/ → /aɾiɡatoː/. "The full form is ありがとうございます."13 おはようございます is おはよう (the adverbial of "early," formal) plus ございます. In casual speech, it may be shortened to just おはよう.12
When a greeting ends in ~うございます, the ~う is a worn-down adjective ending (く → う), and ございます is the polite ある. The everyday "thank you" and "good morning" are literally polite-language constructions.1213
ありがとうございました。11
"Thank you."
Overpoliteness reads as distance or service-speak
でございます can go "anywhere です is used," but in practice it "sounds very formal or stilted."3 ます encodes "politeness toward and distance from the listener." So using the elevated tier with friends or in-group members signals distance rather than warmth.4
The elevated forms are anchored to customer-service contexts. いらっしゃいませ is staff-to-customer speech, and ございます turns up in shop announcements. Using でございます socially can therefore read as clerk-like.1115
です sounds like "des"
The final -u of です is commonly devoiced in standard speech, so です is heard as "des." The phonological rule behind this is vowel devoicing. It has its own dedicated article, so this is only a pointer.
