The 'Want' Rule

Whenever you use 'want' (می‌خواهم), the next verb ALWAYS takes the ب prefix. It's a package deal!
⚠️

The Mi-Space

In digital typing, use Shift+Space for the 'half-space' in می‌شود. It keeps the prefix from looking like a separate word.
💬

Softening Commands

To make a ب command more polite, add 'lotfan' (please) or use the plural form even for one person.

Smart Tips

Check the tense first.

رفتم → می‌روم

Check if it's a command.

نمی‌رو → نرو

Use contractions.

نمی‌دانم → نمیدونم

Use full forms.

نمیدونم → نمی‌دانم

Prononciation

mi-ro-vam

Prefix attachment

The prefix is attached to the stem, sometimes with a zero-width non-joiner.

Question

Rising intonation for yes/no questions.

Mémorise-le

Moyen mnémotechnique

Remember 'M-B-N-N': My Big New Notebook. M for 'می', B for 'ب', N for 'ن', N for 'نمی'.

Association visuelle

Imagine a robot with four buttons on its chest. Pressing 'می' makes it walk, 'ب' makes it stop, 'ن' makes it freeze, and 'نمی' makes it turn off.

Rhyme

Prefixes at the start of the line, make the verb shine every time.

Story

Ali wanted to go to the store. He added 'می' to 'رو' to start walking. But he saw a sign saying 'نرو' (Don't go). He felt sad and said 'نمی‌روم' (I am not going).

Notes culturelles

In formal writing, the 'ب' prefix is always written clearly.

These prefixes evolved from Old Persian particles.
