18+ ( ADULT CONTENT) Ecchi-Etymology and use in Japan:- The correct transcription of the word after Hepburnis "etchi", denoting its usage in Japan. Its current meaning is still closely related to the word " hentai". "Hentai" itself was introduced in the Meiji periodas a term for change of form or transformation in scienceand psychology. In context, it was used to refer to disorders such as hysteriaor to describe paranormal phenomena like hypnosisand telepathy. Further spreading the word led to the connotation ofnon standard. In the 1910s, it was used in sexologyas the compound expression "hentai seiyoku" ,abnormal sexual desire) and became popular within the theory of sexual deviance (Hentai seiyoku ron), published by Eiji Habuto and Jun′ichirō Sawada in 1915. In the 1920s, many publications targeted a broad audience, dealing with deviant sexual appearances, including works related to the Ero Guro Nansensu movement. Matsuzawa calls it a period characterized by a "hentai boom". [In the 1930s began a new western influenced period of censorship which resulted in progressive stop of publication. After the war, in the 1950s, new journals showed an interest in hentai. With this renewed interest, the word hentai is sometimes written in romaji and it was then that H (pronounced asエッチ, as the pronunciation of the English letter H, / ˈ eɪ tʃ /) began to be used as an alternative to "hentai". In 1952, the magazine Shukan Asahi reported that a woman who was groped by a stranger in a movie theater reacted with"ara etchi yo" ("hey, it's a pervert"). In this context, "etchi" must be understood assexually inappropriate and is synonymous toiyarashii( unpleasant, dirty or disgusting) orsukebe ( a pervert). From that moment, the meaning of "hentai" and "etchi" evolved independently. In the 1960s, etchi started to be used by the youth to refer to sex in general. In 1965, a newspaper reported that primary school children using etchi kotoba (the word sexy). In the 1980s, it was used to mean sexas in the phraseetchi suru (to [make] love). The most common theory states that it derives from the first character of the word hentai The word sekkusu is also used in Japan for sex, and Japanese native words for sex (such as seikō) are often replaced by words of foreign origin such as sekkusu or neologisms such as ecchi. Therefore, ecchi is used as a qualifier for anything that is related to erotic or pornographic content. The nuance of ecchi varies with context, but in general, the word itself is comparable to the English words "naughty" or "dirty" (when used as an adjective). In pornographic context, the wordero and other wordings are preferred overetchiby the media. For exampleero-manga, adult anime, or anime / manga for persons over 18 years, and so on. The prefix "H-" is also sometimes used to refer to pornographic genres: H-anime, H-manga, etc.
