When a new reader opens a platform, the first things they see are the rating and genre tags. The rating answers "what's in there"; the genre answers "how will it feel." These are different navigation axes, and both are necessary.
Fanfiction borrowed its genre system from mainstream literature but expanded it. "Romance" in fanfiction isn't the same as a "romance novel" in a bookshop. Fandom has built finer distinctions, and over twenty years it's developed its own vocabulary.
The central conflict is the development of a romantic relationship between characters. The ending isn't necessarily HEA (happily ever after), but the key action is how they relate to each other.
Common subtypes: slow burn (tension builds over dozens of chapters), enemies-to-lovers (conflict becomes romance), friends-to-lovers (the starting point is an existing friendship).

Emotionally heavy content: loss, breakup, guilt, grief. Not necessarily a tragic ending — angst can end in reconciliation, but the path there is painful.
Key difference from hurt-comfort: in angst there's more pain and less relief, or none at all. The reader should be prepared for emotional weight.
Browse angst fics on Fanficia.
The opposite of angst. Soft, warm content without serious conflict. Domestic scenes, first kisses, ordinary mornings together. Rating is usually G or PG-13.
Fluff is often combined with romance, but they're not identical: romance has conflict; pure fluff doesn't.
One character experiences physical or emotional trauma; another provides support. The balance between pain and comfort is the defining feature of the genre.
h/c is one of the oldest fandom genres, rooted in TV fandoms of the 1970s. Its value: the reader gets both emotional weight and relief within the same text.
A comedic genre with deliberately absurd plot turns. Characters become kittens, a magic academy turns out to be a dorm, enemies become office coworkers. Internal logic rules are suspended.
Crack is often combined with intentional OOC — that's part of the genre contract.
Content with heavy themes: violence, manipulation, morally ambiguous characters without redemption. Usually rated R or NC-17. Requires warnings in the tags.
Doesn't mean "general" in the sense of "for everyone." In fandom, gen is a fic without romantic or sexual content as the primary plot. The central conflict is something else: adventure, friendship, character study.
Genre describes the emotional tone and type of conflict. A trope is a specific plot or structural device.
In practice: a work can have one genre and several tropes. Or two genres, if they're compatible: romance + angst, fluff + crack.
Two is the working maximum for most texts. More than two usually means the author hasn't decided what the fic is actually about.
Exception: if one genre is primary and the other is supporting (romance with elements of hurt/comfort — fine; romance + angst + dark + crack — signals an editorial problem).

How does a genre differ from a trope?
A genre is a category of emotional experience (angst, fluff, romance). A trope is a specific plot mechanism (fake dating, soulmates, a hurt-comfort scenario). Genre defines the overall feel of the text; tropes define how the conflict or relationship dynamic is structured.
How many genres should you combine?
Two is standard. One primary and one supporting rarely contradict each other. Three or more often produce an inconsistent tone: the reader doesn't know how to approach the text. If you want to combine more — make sure there's one clearly dominant genre.
Genre and rating are independent axes, but certain combinations are typical:
Knowing these typical combinations is useful in both directions: for tagging your own work and for filtering others'.
Fandom's genre vocabulary keeps evolving. New tropes emerge through popular works: after Twilight the enemies-to-lovers format took a particular shape across fandoms; K-pop fandoms brought idol AU into wide use. The easiest way to track changes is through tags on major platforms.
On Fanficia, genre tags are maintained and updated — the genre catalog shows what's being written now and gives a feel for where fandom is living today. For a first look at the platform, try the generator, pick a favorite genre, and see what comes out.
When you tag "fluff," the reader arrives with a specific expectation: they want to rest, not worry, not feel tense. If your "fluff" contains a sudden tragic death — you've broken that promise. This isn't a question of text quality; it's a question of whether the tag matches the experience.
Genre tags aren't just classification — they're a contract. The reader agrees to a particular emotional experience. The author commits to providing it, or to explicitly warning about any deviation.
Some authors deliberately play with this: they tag "fluff and angst" — and the reader knows a mix is coming. Or "hurt/comfort" — where both pain and relief are promised. The key is precision.
A few practical observations:
The skill of reading tags develops over time. Browse romance works on Fanficia or angst and compare how different authors tag similar content — that's more concrete than any theory. Try the generator — genre selection is built into the process from the start.

Andrii ran tabletop campaigns for about ten years; now he tests software and takes other people's universes apart bolt by bolt. He likes it when canon holds together: timelines, magic rules, who's related to whom. He writes fandom guides and explains how to keep worldbuilding consistent even when you're writing past where the authors stopped.
