The name Tera is believed to have originated from the Sanskrit language, which is one of the oldest Indo-Aryan languages spoken in ancient India. It is derived from the Sanskrit word "tara," which means "star" or "protector." This name has been in use for centuries and has been popular across various cultures and regions.

In Hindu mythology, Tara is the name of a prominent goddess who is revered as the embodiment of compassion and the remover of fears. She is often depicted as a beautiful woman seated on a lotus flower, holding a lotus in one hand and making the gesture of bestowing blessings with the other. The worship of Goddess Tara is particularly popular in Buddhist traditions, where she is considered a female Buddha or enlightened being.

One of the earliest references to the name Tera can be found in the ancient Hindu text, the Mahabharata, which dates back to the 8th or 9th century BCE. In this epic, Tara is mentioned as the name of a celestial nymph who was desired by many gods and sages.

One of the earliest recorded examples is Tera Panth, a 15th-century Indian poet and philosopher who founded the Tera Panth sect of Hinduism. Another prominent figure is Tera Singh Samundari (1822-1892), a Sikh warrior and leader who played a significant role in the Indian Rebellion of 1857 against the British East India Company.

In more recent times, the name Tera has been used across various cultures and nationalities.
