One question asked whether people truly understood the original meaning of certain words. For example, "tsukanu koto" (つかぬこと) actually means "something unrelated to the conversation so far," though many respondents were unsure. Language has always evolved, and the rise and fall of words reflects the times. Expressions such as "kogal" (コギャル), which became popular among high school girls in the late 1990s, or "MD" (エムディー), Sony's MiniDisc released in 1992, have already disappeared from dictionaries. Even "Famicom" (ファミコン), Nintendo's 1983 home console, was among the 1,000 words removed from Sanseido's Dictionary of Words That Disappeared (三省堂『消えたことば辞典』), published in 2023. At the same time, new expressions continue to emerge with every generation. In the latest survey, more than 70 percent of respondents said new words had increased with the spread of SNS (エスエヌエス). Teenagers gave examples such as "shabai" (シャバい), used to describe someone being unavailable or the situation being "uncool," and "aa-ne" (あーね), a shortened way of saying "naruhodo ne" (なるほどね, I see). Others cited "bari kakkee" (バリかっけー), an emphatic version of "cool," and abbreviations like "suki-pi" (スキピ), short for "suki people" (好きピープル), or favourite person. Over 80 percent agreed that abbreviations are on the rise.
