Root and branch; Completely

🌍

Cultural Background

In the arid climate of Iran, maintaining a garden is a battle against the desert. Weeds with deep roots can steal precious water from fruit trees. Thus, 'uprooting' is not just a metaphor but a daily survival task. Traditional Persian buildings use 'Khesht' (mud-brick). If the foundation (bon) is compromised by moisture or salt, the whole building must be razed. You cannot simply patch a mud-brick wall if the base is gone. Poets like Rumi and Hafez often talk about the 'root of sorrow' or the 'foundation of the house of love.' They use these terms to describe the total occupation of the soul by an emotion. In modern Iranian political discourse, the phrase is often used by reformists or revolutionaries to argue that incremental change (eslāh-e jaz'i) is insufficient.

🎯

Pair with 'Kandan'

If you want to sound like a native, use it with the verb 'kandan' (to dig/uproot) when talking about removing bad habits.

⚠️

Too Strong for Small Talk

Don't use this when talking about minor inconveniences; it makes you sound overly dramatic.

Frequently Asked Questions

4 questions

Yes, but usually in the context of a 'fresh start' or 'total renovation.' For example, 'We rebuilt our friendship az bikh o bon.'

It's much stronger. 'Completely' (kāmelan) is a general adverb; 'az bikh o bon' implies you are dealing with the foundation.

Yes, very frequently in classical Persian poetry to describe the destruction of enemies or the uprooting of the heart.

No, the order is fixed. Swapping them sounds like saying 'branch and root' in English—people will understand, but it's wrong.
