📜 Origin
The phrase likely draws from the literal image of being physically bound or restrained, unable to move freely or attend to anything else. By the 19th century, “tied up" had shifted into figurative use in English, describing someone whose time or resources were fully committed elsewhere, much like something (or someone) that's physically restrained can't be used for another purpose. It became especially common in business and scheduling contexts, where being “tied up" meant being unavailable due to other obligations.
