To remove angular or sharp corners and edges from something, making it more rounded or smooth.
From dis- (reversal) + angular (having angles) + -ize (to make). The prefix dis- comes from Latin, while angular derives from Latin angulus meaning 'corner.' The -ize suffix comes from Greek -izein.
This word appears in technical manufacturing and design contexts—when engineers 'disangularize' a product's edges, they're making it safer and more ergonomic, which is why modern phones and devices have those smooth, rounded corners you see today.
