The name Amiyah is a relatively modern variation of the Hebrew name Amiya, which means "God's truth" or "truth of God". It is derived from the Hebrew words "am" (people) and "yah" (a shortened form of the name of the Judeo-Christian God, Yahweh).

The earliest recorded use of the name Amiya dates back to the late 19th century, when it was used as a female name among Jewish communities in parts of Eastern Europe and Russia. However, the name was not particularly common at the time.

As Jewish communities migrated to other parts of the world, such as North America and Western Europe, the name Amiya began to gain more popularity, albeit still relatively rare. The spelling variation Amiyah emerged in the late 20th century, likely as a result of cultural influences and the desire for a more unique or personalized name.

One of the earliest notable individuals with the name Amiya was Amiya Chakravarty (1901-1986), an Indian poet and academic who wrote extensively in Bengali and English. Another early figure with the name was Amiya Nath Bose (1932-2009), an Indian-American statistician and mathematician known for his work in probability theory and stochastic processes.

In more recent times, the name Amiyah has been gaining traction as a popular choice for baby girls, particularly in the United States and parts of the English-speaking world. This may be attributed to its unique sound, the growing interest in names with cultural or religious significance, and the desire for names that are uncommon but still have a meaningful origin.

Some notable individuals with the name Amiyah include Amiyah Scott (born 2002), an American actress and singer known for her roles in television shows and films such as The Walking Dead and The Star. Another is Amiyah King (born 2007), an American actress and model who has appeared in various commercials and television shows.

While the name Amiyah may be relatively new in its current spelling, it carries a rich cultural and linguistic heritage, reflecting the enduring influence of Hebrew names and the desire for names with deeper meanings and connections.
