Meaning
更新 means to update, renew, or refresh something to make it more current or modern. It's commonly used for software updates, refreshing information, renewing documents, or renovating physical spaces. The word combines 更 (gēng, 'to change/more') and 新 (xīn, 'new'), literally meaning 'to change to new.'
Usage
This is a standard formal and informal term used across contexts. It's especially common in technology (app updates, website refreshes), administrative contexts (renewing licenses or documents), and construction (renovating buildings). Native speakers often say 更新一下 to soften the request for an update.
