The Oxford English Dictionary has changed its definition of the word Yid to include a "supporter of or player for Tottenham Hotspur".
The word has frequently been used against Jewish people as an offensive term but over the years has been appropriated by Spurs fans.
Spurs have a strong Jewish following and have been targeted with anti-Semitic abuse by opposing fans.
The club has labelled the new definition as "misleading".
A Spurs spokesman said the club has maintained that "our fans (both Jewish and gentile) have never used the term with any intent to cause offence", and said the OED failed to distinguish the contexts in which the term is and is not offensive.
But Jewish groups said the OED must make clear the word is a "term of abuse".
