People use many different ways to talk. These are called Iranian languages. There are about 86 languages in this group. 
All these languages come from one old ancestor. We call this ancestor Proto-Iranian. Long ago, tribes moved to new lands. They settled in places like Central Asia and the Iranian Plateau. As they moved, their speech began to change.
Experts group these languages into stages. There is Old Iranian, Middle Iranian, and New Iranian. Old Persian was spoken by people in the southwest. Avestan was a sacred language. It was used for religious texts called the Avesta. These languages show how much people's speech can change over time. Today, these languages help people share their stories and cultures.
The Iranian languages are a large family of ways to speak. They belong to the even bigger Indo-European language group. Many people speak these languages natively on the Iranian Plateau. 
Experts group these languages into three main stages of time. The first stage is Old Iranian, which lasted until 400 BCE. The second stage is Middle Iranian, from 400 BCE to 900 CE. The third stage is New Iranian, which began around 900 CE. To understand these, we look at how sounds change. For example, some sounds turn into different sounds over hundreds of years. This is how one ancestor language can turn into many. This process shows how much human speech can grow and shift.
All these languages come from one ancient ancestor called Proto-Iranian. This ancestor language likely started in Central Asia. Some people think it was used by the Andronovo culture. This culture lived around 2000 BCE. As different tribes moved to new lands, their speech changed. They moved into southeastern Europe and the Iranian Plateau. These migrations helped create the many different languages we see today. The way they moved shaped how people talk now.
We have records of some very old languages. Old Persian was spoken by people in the southwest. They lived in a place called Parsa. We can see their writing in the Behistun inscription. Another important language is Avestan. This was a sacred language used for religious texts. These texts are called the Avesta. They belong to the religion known as Zoroastrianism. Avestan is split into Old Avestan and Younger Avestan. These two versions were used in different places and times.
Many Middle Iranian languages were also recorded by historians. Middle Persian came from the Sasanian Empire. Parthian was the language of the Parthian Empire. There was also Bactrian, used by the Kushan and Hephthalite empires. The word "Iran" itself comes from Middle Persian. It was first found in an inscription at Naqsh-e Rostam. Some scholars use the word "Iranic" to describe the whole family. They do this to be very clear about the language group. It is a way to honor the long history of these speakers.
The Iranian languages, also called Iranic languages, form a major branch of the Indo-Iranian family. These languages belong to the much larger Indo-European group. They are spoken natively by many different peoples, primarily on the Iranian Plateau. 
Linguists categorize the development of these languages into three distinct chronological stages. The first is Old Iranian, which lasted until about 400 BCE. The second stage is Middle Iranian, spanning from 400 BCE to 900 CE. The final stage is New Iranian, which has been the dominant form since 900 CE. This progression shows how a single ancestral tongue can evolve through time. As tribes migrated and settled, their speech patterns shifted, creating new branches and dialects.
All Iranian languages descend from a common ancestor known as Proto-Iranian. This ancestor language likely originated in Central Asia. Some scholars suggest it was used by the Andronovo culture during the Bronze Age around 2000 BCE. As Proto-Iranian speakers moved into southeastern Europe, Central Asia, and the Iranian Plateau, the language began to break apart. This process involved specific sound changes. For example, the sound *s often turned into a glottal *h. Other complex shifts occurred with aspirated consonants, which eventually changed into different types of fricatives or unaspirated stops.
Researchers often divide the languages into Western and Eastern branches. The Western Iranian branch includes the Southwestern group, featuring Persian and Luri. It also includes the Northwestern group, where Kurdish is the dominant language. The Eastern Iranian branch includes the Southeastern group, which is led by Pashto. It also contains the Northeastern group, which is the smallest branch and includes Ossetian. Some scholars classify the Avestan languages as Central Iranian. This is because Avestan may have diverged from Proto-Iranian before the east-west split became prominent.
We have direct evidence of several Old Iranian languages through ancient inscriptions. Old Persian was spoken in the southwest by the people of Parsa. We can see its grammar clearly in the Behistun inscription. Another vital language is Avestan, which was used for the liturgical texts of Zoroastrianism. These sacred texts are called the Avesta. Avestan is divided into Old Avestan, which is very archaic, and Younger Avestan. While Old Persian led to Middle Persian, Avestan has no clearly identified Middle Iranian stage. It remained a sacred language, preserving its old characteristics for a long time.
The Middle Iranian period produced several well-recorded languages linked to great empires. Middle Persian was used during the Sasanian Empire. Parthian was the language of the Parthian Empire. Bactrian was spoken within the Kushan and Hephthalite empires. The very name "Iran" comes from Middle Persian. It was first recorded in a third-century inscription at Naqsh-e Rostam. Some scholars use the term "Iranic" to describe the linguistic family. They use this to distinguish the language group from the modern country of Iran.
The scale of the Iranian language family is immense. Persian is one of the most widely spoken, with 92 million native speakers. Pashto follows with 55 million speakers, and Kurdish has 28 million. Other significant languages include Balochi, with 5 to 8 million speakers, and Caspian, with 10 million. Luri is spoken by about 5 million people. Collectively, these languages represent a massive portion of human communication. They connect modern populations to an ancient heritage that stretches back thousands of years.
