Isis is the goddess of magic and healing, wife of Osiris

 Isis (pronounced /ˈaɪ.sɪs/ or eye-sis) was a goddess in Egyptian mythology. She was the sister and wife of Osiris, and they had a son named Horus. Isis also protected children and was one of
 the greatest goddesses. She was also the greatest magician and goddess of magic.

 Origin of the name

The English pronunciation used, /ˈaɪ.sɪs/), comes from the pronunciation of the Greek name, Ίσις, which changed the Egyptian name by adding a final "-s" because of the grammatical requirements of Greek noun endings.

The Egyptian name was recorded as ỉs.t or ȝs.t and meant '(She of the) Throne'. However the true Egyptian pronunciation is not known because their writing system left out vowels. Based on recent studies, the reconstructed pronunciation of her name is *ʔŪsat (ooh-saht). Later, the name in Coptic dialects was "Ēse" or "Ēsi".

To make it easier to say, Egyptologists choose to say the word as "ee-set". Sometimes they may also say "ee-sa". This is because the last "t" in her name was a feminine (female) suffix which is known to have been dropped in speech in the last stages of the Egyptian language

Powers

Isis had great healing powers along with her being a magician and a protector. She could even cast spells on Ra. An example of her powers is when Isis brought Osiris back to life for one night. Though the powers of Isis are strong, there even things she could not do like she could only bring back Osiris to life for a night.
