RESCENE member Woni’s “Museopno” remark has drawn public attention after a June 28 video led to debate over whether the expression should be understood as Gyeongsang dialect or as wording associated by some critics with Ilbe. The Woni dialect controversy widened after a question about the Korean sentence ending “-no” was posted to the National Institute of Korean Language’s Online Ganada board on June 29, prompting a limited linguistic response rather than a definitive judgment. 1
The controversy centers on a scene filmed at RESCENE member Minami’s family home. Reports said a production PD first used “Museopno,” roughly meaning “scary” in the disputed phrasing, and Woni repeated the expression while adding that even the lighting felt scary. 2 Donga Ilbo also reported that Woni later used the standard Korean form “Museowo” when describing fear in the same sequence. 2
Woni’s “Museopno” Remark and How the Dispute Spread

YTN reported that the dispute began from footage of Woni visiting Minami’s family home, where a staff member said “Museopno” and Woni repeated it. 3 The phrasing then became the subject of online debate because the “-no” ending can carry different associations depending on region, context, and listener perception.
The argument was not limited to language specialists or entertainment viewers. Financial News reported that the remark became a debate over whether it was a natural Gyeongsang dialect expression or wording associated with Ilbe, a controversial online community. 4 The same report said MBC Gyeongnam PD Kim Hyun-ji criticized the usage on social media while clarifying that the point was not to define all users as Ilbe users or to censor dialect. 4
YTN described public reaction as divided. Some defended the phrase as ordinary speech from Woni, who is from Geoje, while others argued that people should reconsider language that may hurt others. 3 Financial News also reported that others in the debate argued non-interrogative “-no” usages appear in southeastern dialect contexts, adding another layer to the disagreement over how the sentence should be heard. 4
Language Institute Declines Definitive Judgment
The National Institute of Korean Language became part of the discussion after a question about “-no” was posted to its Online Ganada board. Hankook Ilbo reported that the questioner said they had used forms such as “Museopno” and “Jalhaetno” throughout life in North Gyeongsang, asking whether such expressions were dialect or incorrect usage. 1
The institute’s response did not settle the debate. YTN reported that the institute described “-no” as a Gyeongsang dialect ending used in interrogative sentences, while adding that detailed usage is difficult to state definitively because scholars may differ. 5 Donga Ilbo likewise reported that the institute cited the dictionary definition of “-no” as a Gyeongsang dialect ending, but said detailed usage could not be conclusively stated through Online Ganada. 2
Kookmin Ilbo reported that the institute cited “Urimalsaem,” identifying “-no” as a Gyeongsang dialect ending used in questions with interrogatives, while also noting that actual usage varies depending on scholarly view. 6 Hankook Ilbo summarized the response as declining to give a definitive judgment on the broader usage because the issue exceeded the board’s answer scope. 1
That limited answer is central to the current status of the dispute. The institute did not officially label Woni’s usage as either improper or definitively natural in every context. Instead, the available reports show that it confined its response to dictionary-based explanation and the limits of what its online board could determine.
Why the Debate Remains Unsettled
The case has continued because it sits at the intersection of dialect, online culture, and public sensitivity over language. One side of the reaction emphasizes regional speech patterns, including Woni’s reported background from Geoje and claims that “-no” forms are heard in southeastern dialect settings. 3 The other side focuses on how similar forms can be perceived by listeners who associate them with hostile or exclusionary internet usage.
The dispute also expanded beyond the original video. YTN reported that a documentary PD’s social media post criticizing the usage helped spread the controversy. 3 Kookmin Ilbo reported that the debate around Woni’s remark had also spread into politics, while the National Institute of Korean Language maintained only a limited linguistic response. 6
The available source material does not show a final institutional ruling on whether Woni’s specific sentence was acceptable dialect, offensive usage, or something else. It shows a narrower confirmed record: a June 28 YouTube video, a June 29 Online Ganada question, divided public interpretation, criticism from a media figure, broader political attention, and an official language body saying the matter cannot be stated conclusively through that forum.

The Woni dialect controversy remains unresolved in the reported record because the core question is not only grammatical. It concerns how a regional ending is defined, how it is actually used, and how listeners interpret the same expression in a public entertainment setting.
