Historically it was a regular, non-offensive term but with the Russian influence (compare with Russian жид), it can now be very offensive.

Thought to be from Yiddish kaykl (קײַקל) 'circle'. In the early 20th century, non-English-speaking Jews that immigrated to the United States would sign papers with a circle as opposed to a more common X. The latter symbol was associated by these Jews with the Christian cross, a symbol that, to them, represented millennia of persecution. This is the dominant etymological theory, but there are others, in particular a contraction from the documented phrase ‘Ikey-Kikey’, an American-origin reduplication of Ikey, British-English pejorative for Jews after the prevalence of the name Isaac

The word "jøde" may be used in Norwegian in a fully neutral and descriptive sense, denoting a Jewish person, but is also used as a common anti-Semitic ethnic slur against Jewish people, particularly among young people; it was described as the most common insult among youth in Norway in the 2010s alongside the offensive words "homo" and "hore." Its use as an insult and ethnic slur has been linked to the impact of the Israel-Palestine conflict, and the insult is used by both non-Muslim and Muslim youth. The word is also commonly used, especially by young people, as an offensive insult against people who are not actually Jewish, based on stereotypes of Jewish people, particularly in the sense of a person regarded as greedy.

Даль (3-е изд.) 1: 1345. Over time, the Russian жид acquired a pronounced pejorative meaning (not earlier than the 16th-17th centuries, especially in the 18th century) and became a abusive word. The pejorative words жиды, жидовский in official papers were replaced (at the request of the Jews from Shklov, handed to Catherine II) by евреи, еврейский, which avoided the development of abusive semantics, since they were perceived as an element of bookish, high style.
