Persian Numbers 1-100: Counting Like a Native (یک تا صد)

Place the number before a singular noun and use 'o' to connect tens and units like LEGOs.

Grammar Rule in 30 Seconds

Persian numbers 1-10 are unique, 11-19 are compound, and 20-90 follow a simple 'tens + units' pattern.

  • Numbers 1-10 are unique: 'یک' (yek), 'دو' (do), 'سه' (se), etc.
  • Numbers 11-19 end in '-ده' (dah): 'یازده' (yazdah) is 11.
  • Numbers 20-90 use 'tens + o + units': 'بیست و یک' (bist-o-yek) is 21.
Tens + و (o) + Units

Overview

Ever tried to give your phone number to a new friend in Tehran and suddenly forgot how to say 'seven'? Numbers are the heartbeat of every language. You need them for everything. Ordering three kebabs. Paying for a Snapp (the Persian Uber). Checking if your phone has 5% or 50% battery. In Persian, numbers are surprisingly logical. Once you learn the first ten, you've already won half the battle. Unlike English, where 'eleven' and 'twelve' feel like random words, Persian follows a very strict pattern. You just need the building blocks.
Counting in Persian is your first real superpower. It opens doors to markets, cafes, and making plans. The Persian number system is decimal. It works just like the one you use every day. We use the same digits (0-9), though the symbols look a bit different. In modern Iran, everyone uses Western digits on their phones and computers. But you'll still see Persian digits on street signs and paper menus. Learning to say them is the priority. Whether you are scrolling through Instagram likes or splitting a bill, these numbers are everywhere.

Word Order Rules

Here is the best news you’ll hear all day. In Persian, the number always comes before the noun. Even better? The noun stays singular. In English, we say 'five apples.' In Persian, you say panj sib (five apple). It’s like saying 'five piece of apple.' This makes your life so much easier. You don't have to worry about plural endings like -ha when you're counting. Just drop the number in front and you’re done. If you're talking about people, you might say se nafar (three persons). For objects, we often use a 'counter' word called ta. So, panj ta sib is how you'd actually say it to a friend.

How This Grammar Works

Think of Persian numbers like LEGO bricks. You have your base blocks (1-9). Then you have your 'ten' blocks (10, 20, 30...). To make a number like 25, you just snap them together with a tiny connector. That connector is the sound o (which means 'and'). So, 25 is literally 'twenty and five' (bist o panj). This rule applies to every number from 21 to 99. No weird exceptions. No 'seventy-twelve' like in French. Just pure, mathematical logic. It’s so consistent it almost feels like cheating.

Formation Pattern

1
To master 1-100, follow these three steps:
2
Memorize 1-10: yek, do, se, chahar, panj, shesh, haft, hasht, noh, dah.
3
Learn the 'teens' (11-19): These mostly end in -dah. For example, 13 is sizdah.
4
Learn the tens: bist (20), si (30), chehel (40), panjah (50), shast (60), haftad (70), hashtad (80), navad (90), and finally sad (100).
5
To combine them, take the ten, add o, and then the unit. Example: 42 is chehel o do.

Pattern Variations

Persian has a 'cool' version and a 'formal' version. In books, 15 is panzdah. On the street or in a WhatsApp voice note, people usually say punzdah. The an sound often turns into an un in spoken Persian. This happens with 17 (hefdah vs hifdah) and 19 (nuzdah vs nizdah) too. Don't stress about this yet. If you use the formal version, everyone will still understand you. You'll just sound like a very polite news anchor. Also, keep an eye on the number 1. When counting things, we often use ye instead of yek. Like ye qahve (one coffee) instead of yek qahve.

Real Conversations

Imagine you're at a trendy cafe in North Tehran.

W

Waiter

chi meyl darin? (What would you like?)
Y

You

do ta qahve, lotfan. (Two coffees, please.)
W

Waiter

shod haftad o panj toman. (That's 75 Tomans.)

Or imagine you're texting a friend about a party:

F

Friend

chand nafar miyan? (How many people are coming?)
Y

You

shast nafar! kheyli ziade! (60 people! It's a lot!)

In both cases, the numbers follow the 'Number + Noun' rule perfectly.

Common Mistakes

Don't pluralize the noun! This is the most common trap for English speakers. Never say panj sib-ha. It sounds like you're saying 'five appleses.' Just stay singular: panj sib. Another mistake is forgetting the o connector. bist panj is wrong; it must be bist o panj. Finally, be careful with the number 4 (chahar) and 6 (shesh). In fast speech, chahar often sounds like char. Don't let the speed scare you. Just keep your ears open for that 'o' connector, and you'll always know what the price is.

The 'Ta' Secret

Always use 'ta' when counting things in conversation. 'Se ta sib' sounds much more natural than just 'se sib'.
⚠️

Singular Nouns Only!

Never use the plural suffix (-ha) after a number. It's '10 book', not '10 books'.
💬

Toman vs. Rial

Prices are often written in Rials but spoken in Tomans (1 Toman = 10 Rials). If a kebab is 50,000, they might just say 'panjah' (50).

Smart Tips

Always add 'ta' for informal counting.

Break them into tens and units.

بیستیک بیست و یک

Use ordinal numbers instead.
