Basic Anime Terms You Should Know

If you are a beginner who has just started getting into the world of anime, there may be one thing that feels even more confusing than choosing which anime to watch: the language used by anime fans.

You may have seen someone say something like:

“Wow, the MC is so OP.”

Or:

“That’s not filler. It’s canon.”

Then there are other terms such as isekai, waifu, husbando, otaku, tsundere, yandere, OVA, and ONA.

For longtime anime fans, these terms may sound completely normal.

But if you are new to anime, conversations like these can feel like reading a foreign language.

But don’t worry, you’re not alone. 😄

The world of anime has many specialized terms used to describe characters, genres, storylines, formats, and even fan culture.

The good news is that you don’t need to memorize all of them at once.

In this article, we’ll go through some of the basic anime terms that beginners should know, especially the ones you’re most likely to encounter when watching anime, reading reviews, browsing social media, or talking with other fans.

What Are Anime Terms?

Anime terms are words or expressions commonly used when discussing different aspects of anime and manga.

Some of these terms come from the Japanese language, while others have developed within anime and manga fan communities.

These terms can be used to describe:

• Characters
• Stories
• Genres
• Character abilities
• Anime formats
• Relationships between characters
• Fan culture
• And many other aspects of anime

Understanding basic anime terminology can make it much easier to follow reviews, recommendations, forums, social media discussions, and conversations with other anime fans.

Basic Anime Terms

1. Anime

Anime is a term commonly used to refer to animation from Japan or animation influenced by Japanese animation traditions.

In Japan, the word anime can be used more broadly to refer to different types of animation.

Outside Japan, however, anime is generally used specifically to refer to Japanese animation.

2. Manga

Manga is the Japanese term for comics.

Many anime series are adaptations of manga.

For example, a manga may be published first and later receive an anime adaptation.

However, not every anime comes from a manga.

There are also original anime, where the story is created specifically for animation rather than being adapted from another medium.

3. MC

MC is short for Main Character, meaning the primary character in a story.

For example, in Naruto, Naruto Uzumaki is the main character.

In an anime discussion, you might see someone say:

“The MC in this anime is awesome.”

It simply means:

“The main character in this anime is awesome.”

4. Protagonist

A protagonist is the main character or the character who serves as the central focus of the story.

In many cases, the protagonist is also the MC.

However, the term protagonist focuses more on the character’s role within the story.

5. Antagonist

An antagonist is a character or force that opposes the protagonist or creates conflict for them.

An antagonist does not necessarily have to be an “evil” character.

A character can oppose the protagonist without being completely evil.

Character-Related Terms

6. Waifu

Waifu is a fandom term used to describe a fictional female character whom someone particularly likes or considers their favorite.

The term comes from the Japanese-style pronunciation of the English word “wife.”

In anime communities, someone might jokingly say:

“She’s my waifu.”

This means that the character is one of their favorite female characters.

The term is generally used casually within fandom culture.

7. Husbando

Husbando is essentially the male counterpart to waifu.

The term is usually used to describe a fictional male character whom someone particularly likes or considers their favorite.

It comes from the English word “husband.”

8. Tsundere

Tsundere is a term used to describe a character whose personality contrasts between being cold, harsh, or seemingly uninterested and being caring or affectionate underneath.

Tsundere characters often have difficulty expressing their feelings directly.

This contrast is one of the reasons the tsundere trope has become so popular in anime and manga.

9. Yandere

Yandere refers to a character whose feelings of love or affection are extremely intense and may develop into obsessive or extreme behavior.

Such characters may appear gentle and loving toward the person they care about, while also showing a much more dangerous side under certain circumstances.

Because of this, yandere characters are generally associated with a more extreme form of romantic obsession.

10. Kuudere

Kuudere generally refers to characters who appear calm, emotionally distant, or cold but actually have a softer and more caring side.

Their emotions are often revealed gradually as their relationships with other characters develop.

11. Dandere

Dandere usually describes a character who is quiet, shy, or has difficulty communicating with others.

Once they become comfortable around someone, they may gradually reveal a more open and expressive personality.

Story and Plot Terms

12. Canon

Canon refers to story events or information that are officially considered part of a story’s continuity.

For example, an event that genuinely happens within the main storyline can be described as canon.

This term is important because not every episode or additional story is necessarily part of the main storyline.

13. Non-Canon

Non-canon refers to stories, events, or information that are not considered part of the official main continuity.

The term is often used when discussing additional episodes, alternative adaptations, or material that does not come from the main storyline.

14. Filler

Filler refers to additional story content that generally does not come from the main storyline of the original source material or is created to give the source material more time to progress.

The term is especially common when discussing anime adaptations of manga.

Not all filler is automatically bad.

Some filler episodes can provide additional character moments, side stories, or entertaining situations.

However, some viewers choose to skip filler when they only want to follow the main storyline.

15. Arc

An arc is a section or sequence of a story that focuses on a particular conflict, goal, theme, or character development.

A long-running anime can contain many different story arcs.

For example:

Opening Arc → Next Arc → Major Arc → Final Arc

The term “arc” is extremely common when discussing long-running anime and manga.

16. Spoiler

A spoiler is information that reveals important events in a story to someone who has not experienced it yet.

Examples include revealing:

• A character’s identity
• A character’s death
• The outcome of a battle
• A major plot twist
• The ending of the story

Because of this, anime fans often give a warning before discussing major story details.

If someone says:

“Warning, spoilers!”

it means that the information coming next may reveal an important part of the story.

17. Plot Twist

A plot twist is an unexpected change, revelation, or development in a story that can completely change how viewers understand previous events.

A good plot twist often makes viewers think:

“Oh… so that’s what was really happening!”

Because plot twists are meant to surprise the audience, they should generally not be revealed when recommending an anime to someone who has not watched it yet.

Anime Genres and World-Building Terms

18. Isekai

Isekai literally means “another world.”

In anime and manga, the term is commonly used for stories where a character travels to, is trapped in, or is reincarnated into another world.

The new world may be a fantasy world, a game-like world, or simply a world with completely different rules and systems.

Isekai has become one of the most popular story categories in modern anime.

19. Slice of Life

Slice of Life is a genre that focuses on the everyday lives of its characters.

There does not necessarily need to be a major conflict, fantasy world, or world-ending threat.

The story may focus on:

• School life
• Work
• Friendship
• Family
• Food
• Hobbies
• Everyday activities

The simplicity of these stories is often their main appeal.

20. Mecha

Mecha refers to stories involving robots or large machines, often piloted or controlled by humans.

Mecha anime frequently feature giant robot battles, futuristic technology, military conflicts, or large-scale wars.

21. Ecchi

Ecchi is a term commonly used for works that contain sensual elements or fanservice without focusing on explicit sexual content.

The amount and type of fanservice can vary significantly from one anime to another, so viewers should still pay attention to the appropriate age rating.

Anime Formats

22. OVA

OVA stands for Original Video Animation.

An OVA is an anime originally released directly in video format rather than through regular television broadcasting.

OVAs may contain additional stories, special episodes, side stories, or material that expands upon the main series.

23. ONA

ONA stands for Original Net Animation.

Unlike traditional television anime, ONAs are primarily produced for distribution through the internet.

This format has become increasingly common with the growth of digital streaming platforms.

24. Movie

An anime movie is an animated film created for theatrical release or distributed as a standalone movie.

An anime movie can be part of an existing franchise or tell an original story.

Not every anime movie is a direct continuation of a television series.

25. Special

A special generally refers to an episode or piece of content created outside the regular episode schedule.

It may contain an additional story, comedy segment, recap, or other material related to the main series.

Anime Community Terms

26. Otaku

Otaku is a Japanese term used to describe someone who has an extremely strong or deep interest in a particular subject.

Outside Japan, the term is often used to describe people who are highly interested in anime and manga.

However, the meaning and cultural nuance of the word can vary depending on the context.

So, being an otaku does not simply mean someone who watches anime all day.

27. Cosplay

Cosplay comes from the combination of the words “costume” and “play.”

It refers to the activity of wearing costumes and portraying a particular character, usually from anime, manga, games, movies, or other forms of media.

Someone who participates in cosplay is called a cosplayer.

Cosplay can be done for conventions, photography, competitions, events, or simply as a hobby and form of self-expression.

28. Seiyuu

Seiyuu (声優) is the Japanese term for a voice actor.

In anime, seiyuu provide the voices for characters.

Interestingly, many seiyuu also work as singers, actors, or performers.

Because of this, popular seiyuu can have large fan bases of their own.

Other Popular Anime Terms

29. OP

In anime communities, OP commonly stands for Opening.

The opening is the song and/or animated sequence shown at the beginning of an anime episode.

However, in certain contexts, OP can also mean Overpowered.

That’s why context is important.

For example:

“The OP for this anime is amazing.”

This usually means:

“The opening song/sequence is amazing.”

Meanwhile:

“The MC is OP.”

usually means:

“The main character is extremely powerful.”

30. ED

ED stands for Ending.

The ending is the song and/or animated sequence that usually appears near the end of an anime episode.

Just like an opening, an ending can become an important part of an anime’s identity and fan culture.

31. OP / Overpowered

When used to describe a character, OP means Overpowered.

It means the character possesses abilities or strength that are significantly greater than those of other characters in the story.

For example:

“The MC is so OP.”

This means that the main character is considered extremely powerful.

32. Power Scaling

Power scaling refers to discussions or comparisons about the relative strength and abilities of characters.

For example, fans might debate:

“Who is stronger, Character A or Character B?”

These discussions are especially common in battle shonen anime.

However, power scaling can quickly become complicated because fictional characters’ abilities cannot always be compared using a simple ranking system.

33. MC OP

MC OP means Main Character Overpowered.

Simply put, it describes an anime where the main character possesses power far beyond the average character.

Anime featuring an OP MC are popular because they offer the satisfaction of watching an incredibly powerful protagonist dominate difficult situations.

Commonly Misunderstood Anime Terms

Among all these common terms, there are several that beginners often use incorrectly.

“Shonen Does Not Mean Action”

Shonen is a demographic classification, while action is a genre.

An anime can be classified as shonen while also belonging to genres such as comedy, romance, sports, fantasy, or others.

“Shoujo Does Not Mean Romance”

Just like shonen, shoujo is a demographic, while romance is a genre.

Not every shoujo anime is a romance story.

“Seinen Does Not Mean Dark Anime”

Seinen is a demographic classification, similar to shonen and shoujo.

A dark or mature storyline is only one possible style found in seinen works.

“Josei Does Not Mean Adult Romance”

The same principle applies to josei.

Josei is a demographic, while adult romance is only one of the genres that can appear in josei works.

“Otaku Does Not Simply Mean Someone Who Likes Anime”

The term otaku has a broader meaning and different cultural nuances depending on how it is used.

It can refer to someone with a very strong interest in a particular subject, not exclusively anime.

“Filler Does Not Mean a Bad Episode”

The term filler describes the episode’s relationship to the main storyline or source material.

It does not automatically determine whether the episode is good or bad.

A filler episode can still be entertaining, funny, emotional, or well-written.
