热点 literally means 'hot point' — combining 热 (rè, 'hot') and 点 (diǎn, 'point' or 'spot'). In modern Chinese, it refers to a trending topic or issue that attracts widespread public attention, especially online or in the media. It functions as a noun and is commonly used in discussions about social media, news cycles, and public discourse.

Unlike its literal meaning, 热点 rarely describes physical heat sources (e.g., a warm spot on a stove); instead, it’s almost always metaphorical, indicating cultural, political, or viral relevance. You’ll see it in headlines like '今日热点' ('today’s trending topics') or in phrases like '登上热搜榜的热点' ('a hotspot that made it onto the trending list'). It’s neutral in register but slightly formal or journalistic — more common in writing and broadcast than casual speech.
