In most stories, Uhura is an excellent linguist. Except in "The Undiscovered Country", I guess.
Uhura is never shown to be a linguist in the TV series or movies until J.J. Abrams shows up.
Precisely. It may be a staple of fanon, but the idea that Uhura is some sort of brilliant linguist cannot be found anywhere
in the original TV series or movies. At no time is she ever portrayed as being fluent in Klingon or Romulan or any other alien language.
Onscreen, she's always relied on the Universal Translator just like everybody else.
