Why Anime Has Its Own Vocabulary
If you're new to anime, you've probably already encountered words like shonen, isekai, waifu, or cour and wondered what they mean. Anime culture has developed a rich set of terminology drawn from Japanese language, industry jargon, and internet fan culture. Learning these terms makes discussions with other fans much easier — and helps you understand what you're looking for when searching for something to watch.
Essential Genre Terms
Shonen (少年)
Literally "boy" in Japanese — this refers to anime and manga targeted at young male audiences. Shonen series typically feature action, friendship, and personal growth. Naruto, One Piece, and My Hero Academia are classic examples.
Shojo (少女)
Targeted at young female audiences, shojo series often focus on romance, relationships, and emotional development. Sailor Moon and Fruits Basket are iconic shojo titles.
Seinen (青年)
Aimed at adult men, seinen series tend to be more complex, darker, or mature in theme. Examples include Berserk, Vinland Saga, and Mushishi.
Josei (女性)
Aimed at adult women, josei is similar to shojo but with more realistic and mature romantic scenarios. Nana and Chihayafuru are popular josei works.
Isekai (異世界)
A wildly popular genre where a character is transported to another world — often a fantasy realm resembling a video game. Re:Zero, That Time I Got Reincarnated as a Slime, and Sword Art Online are major isekai titles.
Slice of Life
A genre focused on everyday life and mundane experiences, usually without dramatic conflict. These shows emphasize character interactions and atmosphere. Laid-Back Camp and K-On! are beloved examples.
Production and Format Terms
Cour
A unit of anime broadcast time — typically 12–13 episodes, roughly one quarter of the year. A "two-cour" series runs 24–26 episodes, covering two broadcast seasons.
OVA (Original Video Animation)
Episodes or short films released directly to home video, outside of the regular broadcast schedule. OVAs can be bonus content, side stories, or special episodes.
ONA (Original Net Animation)
Anime released directly to streaming platforms rather than broadcast television.
Simulcast
When an anime episode is released on streaming platforms (like Crunchyroll) at the same time — or close to it — as its Japanese broadcast.
Fan Culture Terms
Otaku (オタク)
A Japanese term for someone with an intense interest in anime, manga, or related media. Originally a somewhat negative label in Japan, it has been largely reclaimed as a badge of pride in Western fan communities.
Waifu / Husbando
Fan terms for a fictional character someone considers their favorite or feels a strong attachment to. "Waifu" is used for female characters, "husbando" for male characters. These terms are used affectionately and humorously.
Canon
Events, relationships, or facts that are officially established within a series' story. Anything that happens in the official manga or anime is "canon." Fan theories and fanfiction are not canon.
Filler
Episodes or arcs that are not present in the source material (usually manga), created by the anime studio to buy time. Filler doesn't advance the main plot.
Sub vs. Dub
Sub (subtitled) means watching in the original Japanese with subtitles. Dub means watching a version with dialogue re-recorded in another language (usually English). Both are valid ways to enjoy anime — it's a personal preference.
Getting Started
You don't need to memorize all of this at once. As you watch more anime and engage with the community, these terms will become second nature. The most important thing is to just start watching — pick a genre that sounds interesting and dive in. The community is welcoming to newcomers, and there's always something new to discover.
