What does fansub mean?
A fansub is a subtitle for a film, television episode, or similar work that is created and distributed by fans rather than by an officially licensed publisher. The word blends "fan" with "subtitle" and emerged from the anime communities of the 1980s and 1990s, when enthusiasts translated Japanese animation that no Western company had licensed. Fansubs made vast amounts of otherwise inaccessible media available to international audiences, and the practice is widely credited with building the overseas demand that later brought anime mainstream commercial success. Because fansubs are distributed without permission, they occupy a legally ambiguous position, yet they are generally viewed within fan culture as acts of devotion rather than simple piracy. Related terms include "fansubber," a person who makes them, and "fansubbing," the activity itself. Today the word persists mainly among collectors and viewers of niche or untranslated releases.
A fan-made subtitle or subtitled copy of a foreign film or television program, especially anime, produced without authorization from the rights holder.
"The series was only available overseas thanks to a dedicated fansub."
Often used loosely to refer to the subtitled video file itself, not just the subtitle track.
To produce or distribute a fan-made subtitle for a media work.
"A small team of volunteers fansubbed the entire season within weeks."
Less common than the noun form.
Standard pluralization; commonly used when discussing collections or distributions of multiple fan-subtitled works.
"The archive contains hundreds of fansubs from defunct translation groups."
Before streaming giants licensed anime worldwide, entire global fandoms ran on volunteers who translated episodes within hours — unpaid, uncredited by any studio, and technically illegal.

Etymology of fansub
The word fansub is a compound of "fan," itself derived from "fanatic," and "subtitle," referring to text displayed over moving images. It originated in English-speaking anime fan communities during the late twentieth century, when volunteers began adding homemade translations to imported Japanese videotapes. From the headword come the derivative terms fansubber (a person who creates fansubs) and fansubbing (the activity), both formed by regular derivation.
