B1 Idiom Informal

سر به نیست کردن

sar be neest kardan

To eliminate someone/something

Meaning

To secretly get rid of or destroy a person or object.

🌍

Cultural Background

In Iranian noir cinema, this phrase is a staple. It reflects the 'Zir-zamini' (underground) nature of conflict in urban settings. Classical poets often used 'Nist' to describe the spiritual annihilation of the ego, but the idiom brings this lofty concept down to the gritty world of crime. The phrase is also understood and used in Afghanistan, often in the context of the long years of conflict and disappearances. While 'Napadid kardan' is more common in formal Tajik, 'Sar be nist' is recognized through the influence of Iranian media.
