question: Why do all languages say "haha" when laughing? Is laughing a natural thing? And if so, how come animals dont laugh?
comment: Languages say "haha" or "hehe" because it's the sound humans make when laughing. It's a natural thing. [Animals laugh]( URL_1 ) too, but it does require a certain level of evolution / intelligence, because what's funny requires understanding and "getting" the joke. There are several [theories of "what's funny"]( URL_0 ) that you can read about.
passages: The Czech and Slovak ironic love of language contributed to the distribution of "ahoj". In Slovakia "ahoj"-derivates are used in variety of different scenarios, such as the diminutive "ahojček", as a toast "ahojka", to a greater extent the plural-form "ahojte", as well as the grammatically correct we-form "ahojme sa". In Czech as well as in Slovak "ahoj" is being slowly replaced by the modern-day form "čau", which comes from the Italian greeting "ciao". This has been perceived to be the case since the Czechoslovak government allowed the Italian films to be shown in the 1960s.
   "Woh Kaun Thi?" was released in 1964, a black-and-white Psychological mystery film directed by Raj Khosla. It starred Sadhana, Manoj Kumar and Prem Chopra and the screenplay was written by Dhruva Chatterjee. The music Madan Mohan was an asset to the movie. The film became a hit at the box office. Raj Khosla directed Sadhana in two more suspense thriller movies, namely: "Mera Saaya" (1966) and "Anita (1967 film)". The ghost singing song "Naina Barse Rimjnim Rimjhim" was sung by Lata Mangeshkar and lyrics were written by Raja Mehdi Ali Khan.

   BULLET::::- wkwkwk: in Indonesian, "wkwkwk" is often used to express laughter. A new variant, "Akwoakwoak" or "Awkwoakwoak" is often used beside the original version. Both original and new variant are originated from how Donald Duck laughing, which is sounding "Wakakaka".
  
  BULLET::::- חחח/ההה: Hebrew version of LOL. The letter ח is pronounced [/x/ /x/] and ה is pronounced [/h/ /h/]. Putting them together (usually three or more in a row) makes the word khakhakha or hahaha (since vowels in Hebrew are generally not written), which is in many languages regarded as the sound of laughter.
   In one particular case "Åhoi" is used as an instruction to the cattle to slow down. It was found before World War I in the Ore Mountains and it was used in the same way as "eha" and "oha, ooha(a)." It is possible that this is a combination of two interjections, as in Middle English, though "eha" might come from the typical Ore Mountain form "eh" "ein, inne", as "ee halten" "an-, ein-, innehalten". The new standard dictionary for this language area lacks an entry for "åhoi, ahoi" or "oho." In a valley in the Slovenian Triglav area shepherds use the call "Ohoi!" to communicate over long distances, according to a report from 1838.
   The "Wer da", or "Who's there?", the phrase he introduced once was not new. In 1824 and 1827 the German editions of Cooper's story "The Pilot" were released, in which "ahoi" was translated with similar expressions, such as "Wer da!", "Wer da?", "heda" or "He! He!". Not until 1842 in "der Lotse" (English, the pilot) ahoy became the standard interjection due to Eduard Mauch's translation, however this contained four "ahoy"s and one "ahoi".
   Woh Kaun Thi?
  
  Woh Kaun Thi? (English: "Who Was She?") is a 1964 Indian Hindi-language black-and-white psychological mystery film directed by Raj Khosla, starring Sadhana, Manoj Kumar and Prem Chopra. Though the screenplay was written by Dhruva Chatterjee, parts were later rewritten, wherein Manoj Kumar took an active role. Music by Madan Mohan was the asset of this movie. The film became a hit at the box office. Its success had Khosla directing Sadhana in two more suspense thrillers: "Mera Saaya" (1966) and "Anita" (1967).

  The Passive Aspect of Heru-ra-ha is Hoor-pa-kraat (, meaning "Horus the Child"; Egyptological pronunciation: "Har-pa-khered"), more commonly referred to by the Greek rendering "Harpocrates"; Horus, the son of Isis and Osiris, sometimes distinguished from their brother Horus the Elder, who was the old patron deity of Upper Egypt. Hoor is represented as a young boy with a child's sidelock of hair, sucking his finger. The Greeks, Ovid and the Hermetic Order of the Golden Dawn attributed silence to him, presumably because the sucking of the finger is suggestive of the common "shhh"-gesture.
   The stem rakh-, meaning 'laugh', may take the derivational affix -ohw and become rakhohw-, or 'laugh at'. Thus, -ohw serves to create an impersonal transitive verb theme with rakh- as the stem. There are many derivational affixes, most of which correspond to a complicated set of rules: stems can belong to one of eleven categories that determines which set of derivational affixes it may take. Therefore, to form an impersonal transitive verb theme like rakhohw, for example, there are 10 other possible affixes that occur with stems from other categories. Furthermore, certain derivational affixes occur only when affixed to specific stems.
   Human sounds sometimes provide instances of onomatopoeia, as when "mwah" is used to represent a kiss.
  
  For animal sounds, words like "quack" (duck), "moo" (cow), "bark" or "woof" (dog), "roar" (lion), "meow"/"miaow" or "purr" (cat), "cluck" (chicken) and "baa" (sheep) are typically used in English (both as nouns and as verbs).
   The anglicized name Isaac is a transliteration of the Hebrew term "Yiṣḥāq" (יִצְחָק) which literally means "He laughs/will laugh." Ugaritic texts dating from the 13th century BCE refer to the benevolent smile of the Canaanite deity El. Genesis, however, ascribes the laughter to Isaac's parents, Abraham and Sarah, rather than El. According to the biblical narrative, Abraham fell on his face and laughed when God (Hebrew, "Elohim") imparted the news of their son's eventual birth. He laughed because Sarah was past the age of childbearing; both she and Abraham were advanced in age. Later, when Sarah overheard three messengers of the Lord renew the promise, she laughed inwardly for the same reason. Sarah denied laughing when God questioned Abraham about it.
   The relation of "ahoi" and "hoi", which is a common form of address in Dutch, is unclear. "Hoi", which had been proven to be an exclamation of joy as early as 1552, could also be a short form of "ahoi" or "ahoi" could be an extension of "hoi". Most likely "hoi" belongs to a group of calls such as "hó" and "hé" and is not closely related to "ahoi" at all.

   BULLET::::- Hooah is the war cry of the United States Army and Oorah is a war cry used by United States Marine Corps. The Slavic version, "Ura!" has been used by the Imperial Russian Army, the Red Army and is still used by the Russian Ground Forces, alongside many more Eastern European armed forces. It was also used by Yugoslav Partisans as Juriš/Јуриш.

   Webster's dictionary from 1913 traces the etymology of "holloa" to the Old English "halow" and suggests: "Perhaps from ah + lo; compare Anglo Saxon ealā."
  
  According to the "American Heritage Dictionary", "hallo" is a modification of the obsolete "holla" ("stop!"), perhaps from Old French "hola" ("ho", ho! + "la", there, from Latin "illac", that way).
   and formulated it as such: "The young eagle was prepared for a new journey through the clear waves; the crew let out its cheerful shout of Hiaho." In the English translation of 1844 it was however, "The crew of the young Eagle […] shouted their cheerful ahoys." In 1846 Flygare-Carlén wrote "Båt, ohoj – hvarifrån, hvathän?", English "Ship, ahoy - where from, where to?" But in English-Danish dictionaries from 1863, "ahoy" is given as "Hey! Holla!" und "holla! heida!"

   The earliest creditable use of the word "ahoi" dates back to 1828. In 1827 the American story-teller James Fenimore Cooper published his pirate story "The Red Rover". The following year "der rothe Freibeuter" was released in Frankfurt am Main. The translator Karl Meurer did not translate all of the words. The command "All hands make sail, ahoy!" was translated as "Alle zu Hauf! Die Segel hißt!", but later on in the novel "ahoy" was translated as "aho", which could have been a moment of inattention. However, Meurer translated the phrase "All hands to mischief, ahoy!", as a signalled approval of amusement on board and so became "Alle zu Hauf! zu Possen, ahoi!". Meurer also translated the phrase "Good humour, ahoy!" with "Bei den Possen gehalten, ahoi!"
   In comic books, where supervillains utter such laughs, they are variously rendered as "mwahahaha", "muwhahaha", "muahahaha", "bwahahaha", etc. (Compare with "Ho ho ho".) These words are also commonly used on internet blogs, bulletin board systems, and games. There, they are generally used when some form of victory is attained, or to indicate superiority over someone else (ownage), or also mockingly at a statement one finds hard to believe was uttered in earnestness. The words are often used as interjections, and less frequently as nouns.
   Within its performance frame, joke-telling is labelled as a culturally marked form of communication. Both the performer and audience understand it to be set apart from the "real" world. "An elephant walks into a bar…"; a native English speaker automatically understands that this is the start of a joke, and the story that follows is not meant to be taken at face value (i.e. it is non-bona-fide communication). The framing itself invokes a play mode; if the audience is unable or unwilling to move into play, then nothing will seem funny.

  Section::::Plot.
   Numerous folk tales about prehistoric times all begin with the phrase "Deenaadai' ", which translates roughly as "In the ancient days". This is usually followed with the admission that this was "when all of the people could talk to the animals, and all of the animals could speak with the people". These stories are often parables, which suggest a proper protocol, or code of behavior for Gwichʼin. Equality, generosity, hard work, kindness, mercy, cooperation for mutual success, and just revenge are often the themes of stories such as: "Tsyaa Too Oozhrii Gwizhit" (The Boy In The Moon), "Zhoh Ts'à Nahtryaa" (The Wolf and the Wolverine), "Vadzaih Luk Hàa" (The Caribou and the Fish).
   "Eh?" used to solicit agreement or confirmation is also heard regularly amongst speakers in Australia and the United Kingdom (where it is sometimes spelled "" on the assumption that "eh" would rhyme with "" or ""). In the Caribbean island of Barbados the word "nuh" acts similarly, as does "noh" in Surinamese Dutch and Sranantongo. The usage in New Zealand is similar, and is more common in the North Island. It is also heard in the United States, especially Minnesota, Wisconsin, the Upper Peninsula of Michigan (although the Scandinavian-based Yooperism "ya" is more common), Oklahoma and the New England region. In New England and Oklahoma, it is also used as a general exclamation as in Scotland and the Channel Islands of Jersey and Guernsey.
   BULLET::::- ههههه: Arabic script repetition of the "هـ" character meaning "Hahahaha" or "Hehehehe". "هـ" is equivalent to the letter "H". The equivalents of the "a" or "e" short vowels are Arabic diacritics and are optional to write.
  
  BULLET::::- "ㅋㅋㅋ" ("kkk" or "kekeke") and "ㅎㅎㅎ" ("hhh") are usually used to indicate laughter in Korean. 'ㅋ', is a Korean Jamo consonant representing a "k" sound, and 'ㅎ' represents an "h" sound. Both "ㅋㅋㅋ" and "ㅎㅎㅎ" represent laughter which is not very loud. However, if a vowel symbol is written, louder laughter is implied: "하하" "haha" "호호", "hoho."
   BULLET::::- Yo-he-ho. The "yo-he-ho" theory saw language emerging out of collective rhythmic labour, the attempt to synchronise muscular effort resulting in sounds such as "heave" alternating with sounds such as "ho". Believed to be derived from the basis of human collaborative efforts, this theory states that humans needed words, which might have started off as chanting, to communicate. This need could have been to ward off predators, or served as a unifying battle cry.
   Ojha (expression)
  
  Ojha or oj-ha () is a common Serbian/Montenegrin emotional expression and interjection. It is frequently used during celebrations such as weddings or traditional dancing. It is very connected to Montenegrin culture and the ethos of Montenegrins, often used in Montenegro-themed songs as well as topics concerning Montenegrins, used to convey excitement or ironic mockery. 
   The difference in language often results in miscommunication, as seen in an onomatopoeic example, "555", which sounds like "crying" in Chinese, and "laughing" in Thai. A similar example is between the English "haha" and the Spanish "jaja", where both are onomatopoeic expressions of laughter, but the difference in language also meant a different consonant for the same sound to be produced.
