Where it came from
What 也 first meant, how it became a function word, and where it stands today.
The origin of the character is genuinely disputed — one old account sees a loan from 匜, a pouring basin; none is certain — and the particle use is as old as the record. Classical 也 owned the business of assertion for a thousand years. In the medieval vernacular that work passed to new finals like 了 and 呢, and the freed-up character was recruited, by Tang times, for the adverb it is today: "also" — a job it never once does in the Analects. Few characters have swapped meanings so completely while never leaving daily speech.

1Declarative particle341× · 64%
Classical Chinese has no word for "is" (no copula) in sentences like "governing is setting straight" — the two halves simply stand side by side, and 也 at the end seals them together as a judgment (a declaration): 政者，正也. When you read 是⋯也, the "is" in your English comes from the 也, not from the 是.
Gloss is; it is so (supplies the English "is")
Look for sentence-final, very often paired with 者 after the first half: X者，Y也.
Technical final particle marking a statement as an assertion or judgement, often equivalent to is

子入大廟，每事問。或曰：「孰謂鄹人之子知禮乎？入大廟，每事問。」子聞之曰：「是禮也。」
The Master, when he entered the grand temple, asked about everything. Some one said: "Who will say that the son of the man of Zou knows the rules of propriety! He has entered the grand temple and asks about everything."
The Master heard the remark, and said: "This is a rule of propriety."
Legge 1861
Word by word 是禮也 — “THIS is ritual”
也 closes a bare identification.
季康子問政於孔子。孔子對曰：「政者，正也。子帥以正，孰敢不正？」
Ji Kang asked Confucius about government. Confucius replied: "To govern means to rectify. If you lead on the people with correctness, who will dare not to be correct?"
Legge 1861
Word by word 政者，正也 — “Governing means setting straight”
The 者⋯也 frame: topic named, then defined.
子曰：「由！誨女知之乎？知之為知之，不知為不知，是知也。」
The Master said: "You, shall I teach you what knowledge is? When you know a thing, to hold that you know it; and when you do not know a thing, to allow that you do not know it; — this is knowledge."
Legge 1861
Word by word 知之為知之，不知為不知，是知也 — “To know what you know and know what you don't know - this IS wisdom”
也 marks the conclusion as a definition
2Topic pause161× · 30%
Sets off what the sentence is about (its topic) before anything is said about it — like the comma in "As for Chai, he is slow." Often after names and time phrases.
Gloss as for⋯ (a pause; no English word)
Look for mid-sentence after a name or time phrase, often answered by a matching 也 clause.
Technical particle marking a pause after a topic, subject, or subordinate clause before the comment that follows
4 examples
柴也愚，參也魯，師也辟，由也喭。
Chai is simple. Shen is dull. Shi is specious. You is coarse.
Legge 1861
Word by word 柴也愚，參也魯，師也辟，由也喭 — “Chai is slow, Shen is dull, Shi is one-sided, You is coarse”
也 after each name: four topics in a row — "as for Chai… as for Shen…" English has no pause to match, so each 也 surfaces as the "is" that joins name to comment.
有子曰：「其為人也孝弟，而好犯上者，鮮矣；不好犯上，而好作亂者，未之有也。君子務本，本立而道生。孝弟也者，其為仁之本與！」
The philosopher You said: "They are few who, being filial and fraternal, are fond of offending against their superiors. There have been none, who, not liking to offend against their superiors, have been fond of stirring up confusion.
The superior man bends his attention to what is radical. That being established, all practical courses naturally grow up. Filial piety and fraternal submission! — are they not the root of all benevolent actions?"
Legge 1861
Word by word 其為人也孝弟 — “As for his being a person, he is filial and respectful”
也 marks 其為人 as the topic: "as for his character…" Lau words the seam itself: "a man whose character IS SUCH THAT he is good as a son…" Legge's "being" is instead the 為 of 為人, the pause absorbed.
有子曰：「其為人也孝弟，而好犯上者，鮮矣；不好犯上，而好作亂者，未之有也。君子務本，本立而道生。孝弟也者，其為仁之本與！」
The philosopher You said: "They are few who, being filial and fraternal, are fond of offending against their superiors. There have been none, who, not liking to offend against their superiors, have been fond of stirring up confusion.
The superior man bends his attention to what is radical. That being established, all practical courses naturally grow up. Filial piety and fraternal submission! — are they not the root of all benevolent actions?"
Legge 1861
Word by word 孝弟也者，其為仁之本與 — “Filial piety and brotherly respect - are they not the root of benevolence?”
也者 doubles the pause: the topic named, then held up. The sentence itself ends in the question particle 與, not 也.
宰予晝寢。子曰：「朽木不可雕也，糞土之牆不可杇也，於予與何誅。」子曰：「始吾於人也，聽其言而信其行；今吾於人也，聽其言而觀其行。於予與改是。」
Zai Yu being asleep during the daytime, the Master said: "Rotten wood cannot be carved; a wall of dirty earth will not receive the trowel. This Yu! — what is the use of my reproving him?"
The Master said: "At first, my way with men was to hear their words, and give them credit for their conduct. Now my way is to hear their words, and look at their conduct. It is from Yu that I have learned to make this change."
Legge 1861
Word by word 始吾於人也，聽其言而信其行；今吾於人也，聽其言而觀其行 — “At first, with people, I heard their words and trusted their deeds; now, with people, I hear their words and watch their deeds”
也 closes each topic — "at first, with people…", "now, with people…" — and the sentence carries on.
3Explanatory particlecounted within the senses above
Ends a sentence that gives a reason (an explanation), with the feel of "you see" or "that is why". Often after 是以, "that is why", which announces the explanation 也 then closes.
Gloss you see; that is why (usually no English word)
Look for closing a clause that answers "why?", often opened by 是以.

王孫賈問曰：「與其媚於奧，寧媚於竈，何謂也？」子曰：「不然，獲罪於天，無所禱也。」
Wangsun Jia asked, saying: "What is the meaning of the saying, 'It is better to pay court to the furnace than to the south-west corner?'"
The Master said: "Not so. He who offends against Heaven has none to whom he can pray."
Legge 1861
Word by word 無所禱也 — “there is nowhere left to pray”
也 closes the reason, and its causative force is what Lau's "When" (Roberts' "If") writes at the FRONT: offend Heaven, and — this being why — there is nowhere to pray. English marks at the head of the condition what Chinese seals at its end. (Watson's exclamation mark carries the same finality as pure tone.)
長沮、桀溺耦而耕，孔子過之，使子路問津焉。長沮曰：「夫執輿者為誰？」子路曰：「為孔丘。」曰：「是魯孔丘與？」曰：「是也。」曰：「是知津矣。」問於桀溺，桀溺曰：「子為誰？」曰：「為仲由。」曰：「是魯孔丘之徒與？」對曰：「然。」曰：「滔滔者天下皆是也，而誰以易之？且而與其從辟人之士也，豈若從辟世之士哉？」耰而不輟。子路行以告。夫子憮然曰：「鳥獸不可與同群，吾非斯人之徒與而誰與？天下有道，丘不與易也。」
Changju and Jieni were at work in the field together, when Confucius passed by them, and sent Zilu to inquire for the ford.
Changju said: "Who is he that holds the reins in the carriage there?" Zilu told him: "It is Kong Qiu." "Is it not Kong Qiu of Lu?" asked he. "Yes," was the reply, to which the other rejoined: "He knows the ford."
Zilu then inquired of Jieni, who said to him: "Who are you, sir?" He answered: "I am Zhongyou." "Are you not the disciple of Kong Qiu of Lu?" asked the other. "I am," replied he, and then Jieni said to him: "Disorder, like a swelling flood, spreads over the whole empire, and who is he that will change its state for you? Than follow one who merely withdraws from this one and that one, had you not better follow those who have withdrawn from the world altogether?"
With this he fell to covering up the seed, and proceeded with his work, without stopping. Zilu went and reported their remarks, when the Master observed with a sigh: "It is impossible to associate with birds and beasts, as if they were the same with us. If I associate not with these people — with mankind — with whom shall I associate? If right principles prevailed through the empire, there would be no use for me to change its state."
Legge 1861
Word by word 天下有道，丘不與易也 — “If the Way prevailed in the world, I would not be seeking to change it”
也 seals the reason Confucius gives for staying among men. Chin alone words the force it carries — "The world has a moral way, SO I will not change places" — his "so" medial where the 也 is final, but doing its work.
子曰：「富與貴是人之所欲也，不以其道得之，不處也；貧與賤是人之所惡也，不以其道得之，不去也。君子去仁，惡乎成名？君子無終食之間違仁，造次必於是，顛沛必於是。」
The Master said: "Riches and honors are what men desire. If it cannot be obtained in the proper way, they should not be held. Poverty and meanness are what men dislike. If it cannot be avoided in the proper way, they should not be avoided.
If a superior man abandon virtue, how can he fulfill the requirements of that name?
The superior man does not, even for the space of a single meal, act contrary to virtue. In moments of haste, he cleaves to it. In seasons of danger, he cleaves to it."
Legge 1861
Word by word 不以其道得之，不處也 — “if not gotten by the proper Way — he does not dwell in them”
The same shape as 3.13: a bare conditional whose 也 seals the consequence, and English opens it with "If". Half the translators write that If; the Chinese writes 也 at the far end instead.
Also counted in the book — rarer, and not always a function word:
4Question particle30× · 6%
Look for clause-final in a question, usually with a question word like 何; also in the combinations 也與 and 也哉
Technical final particle marking the clause as a question, usually a yes or no or rhetorical question
3 examples
子張問：「十世可知也？」子曰：「殷因於夏禮，所損益，可知也；周因於殷禮，所損益，可知也；其或繼周者，雖百世可知也。」
Zizhang asked whether the affairs of ten ages after could be known.
Confucius said: "The Yin dynasty followed the regulations of the Xia: wherein it took from or added to them may be known. The Zhou dynasty has followed the regulations of Yin: wherein it took from or added to them may be known. Some other may follow the Zhou, but though it should be at the distance of a hundred ages, its affairs may be known."
Legge 1861
interrogative final particle marking a yes/no question
子貢問曰：「賜也何如？」子曰：「女器也。」曰：「何器也？」曰：「瑚璉也。」
Zigong asked: "What do you say of me, Ci?" The Master said: "You are a utensil." "What utensil?" "A gemmed sacrificial utensil."
Legge 1861
In a word none of the eight translators gives this 也 an English word — its work is done by tone and structure.
final particle marking a question following an interrogative word
孟懿子問孝。子曰：「無違。」樊遲御，子告之曰：「孟孫問孝於我，我對曰『無違』。」樊遲曰：「何謂也？」子曰：「生事之以禮；死葬之以禮，祭之以禮。」
Meng Yizi asked what filial piety was. The Master said: "It is not being disobedient."
Soon after, as Fan Chi was driving him, the Master told him, saying: "Mengsun asked me what filial piety was, and I answered him, 'not being disobedient.'"
Fan Chi said: "What did you mean?"
The Master replied: "That parents, when alive, be served according to propriety; that, when dead, they should be buried according to propriety; and that they should be sacrificed to according to propriety."
