砍掉 (kǎn diào) is a verb meaning 'to cut off' or 'to eliminate', literally combining 砍 (to chop, hack, or cut down with force) and 掉 (a resultative complement indicating removal or disappearance). It implies decisive, often physical, removal — typically of something attached, growing, or obstructive, such as branches, weeds, or unnecessary parts. The action usually involves tools like an axe or machete and carries a sense of finality.

This verb is commonly used in agricultural, gardening, construction, or administrative contexts — for example, cutting down overgrown trees, removing redundant staff, or deleting unwanted files (figuratively). While it can be used metaphorically, its core image remains concrete and forceful. It’s neutral in register but may sound blunt or harsh depending on context — especially when applied to people or abstract systems — so tone and context matter for politeness.
