 Anime Original (AO)/ Anime Exclusive

- Dubbing is the process of re-recording and/or replacing voices of a video. This is most often done to air the show in another language. At a minimum, the original voice actors are replaced with native language actors, but sometimes the soundtrack, dialogue, and even whole scenes are replaced depending on what the licensing company sees fit to change. This can create disparity from the source work; the English language Funimation Entertainment dub, Case Closed, changed many of the character names.
 Golden Week
- Golden Week (ゴールデンウィーク Gōruden Wīku), also known as Ōgata renkyū (大型連休 ) or Ōgon shūkan (黄金週間 ), is a Japanese term applied to the period containing a number of almost successive public holidays. See main article.
- A word or expression with connotations conveying esteem or respect when used in addressing or referring to a person. In Japanese, honorifics are mandatory and pervasive, and signify the relationship between people using them. It is sometimes difficult to find an appropriate English equivalent that sounds natural, so they are sometimes left untranslated. For a list of honorifics and what they imply please see Wikipedia.
- Kanji (漢字 ) are the Chinese characters that are used in the modern Japanese writing system along with hiragana (ひらがな, 平仮名), katakana (カタカナ, 片仮名), Indo Arabic numerals, and the occasional use of the Latin alphabet (known as the Romanization of Japanese, or "Rōmaji").
- An older episode which has had the quality of its sound and/or picture enhanced. Sometimes various scenes are added, removed, or changed. When used in the Detective Conan fandom, it often implies that the weekly timeslot for Detective Conan is rerunning a remastered episode instead of showing new content. See the category for a list of all remastered episodes.
- A method of taking the Japanese written language and approximating it using the Latin alphabet so it is more readable to English speakers. There are many different styles of romanization. The output of romanization is called "Rōmaji".
- Seiyū (声優 ) is Japanese for "voice actor".
- Sub is a shorthand for subtitled episode as opposed to a dubbed episode. The original voice acting, dialogue, and soundtrack are preserved, while a translation is displayed over part of the screen.
- Shōnen (少年 少年), shonen, or shounen, is a Kanji word literally meaning few years and generally referring to a typical boy, from elementary school through high school age.
