Ambiguous/Open Ending — Tag Meaning
Warns that the story deliberately withholds resolution: the fate of the characters, the relationship, or the world is left to the reader's interpretation. Authors use it for artistic effect and tag it so readers who need closure can steer clear — open endings are divisive enough that the warning matters.

Hopeful Ending
Marks the middle ground where things aren't fixed but they're turning toward the light — the couple hasn't reunited yet but the door is open, recovery has begun, dawn is implied. Authors use it when Happy Ending would overpromise but the story is far from bleak.

Bittersweet Ending
An ending-spoiler tag, courteously provided: the conclusion mixes resolution with loss. Something is gained and something is given up — a character survives but the relationship doesn't, the war is won but not for everyone. It sits deliberately between Happy Ending and Sad Ending in fandom's truth-in-labeling system.

Sad Ending
The honest counterpart to Happy Ending: this story concludes in loss, separation, or grief, and the author is telling you up front. Tagging it is considered basic courtesy on AO3, since an unmarked sad ending is one of fandom's cardinal reading betrayals.

Character Study
A fic whose project is understanding one character deeply — their psychology, history, contradictions — rather than telling an eventful story. Often written about complex or underexplored characters, these pieces function as essays in narrative form and are prized in fandoms with rich casts.
