What are the differences between magical humans such as wizards witches warlocks sorcerers druids etc?

ANSWER

There is a distinct difference in all of these terms, historical and real.

A wizard (wyzard) is a male practicer of magic(k). Often this title was used interchangeably with witch. In the middle ages, the title became more common with users of HIGH magic(K), or what is known as ceremonial magic(k). This was different from the magic(k) practiced by many people of the heath, known as heathens or pagans, who tended to practice low or natural herbal magic which relied less on christian and Hebrew themes and overtones and more on nature spirits.

A Magician historically was not sex specific and was applied to either males or females who practice a form of magic(k). In time it has been used almost exclusively to mean stage magicians, who use illusions and slight of hand to appear to obtain some sort of occult knowledge. But a practicing magician, not a stage magician, is simply a practitioner of magic(K).

A shaman is someone, often in more tribal groups, who is a spiritual healer of sorts, who often heals by communicating with otherworldly spirits or energies to heal the ailments in a person's spiritual being which in effect heals the person's physical bodies. They may also work as intermediaries or spiritual leaders of their communities like priests or clerics. They often do not practice other forms of magic beside the more spiritual healings and some protections for their tribes or clients.

A sorcerer is a practitioner of magic(K), male or female with the female version of the Word often being sorceress but sorcerer is still appropriate, but this label has been historically associated with malicious intent, so someone who uses magic(k) for ill or for negative ends. (also sorcerers are also associated with conjurations and not just ritual magic(k) or talisman work though a sorcerer may be proficient in both.

A warlock is a badly used term. People ignorantly use it interchangeably for the male version of the Word witch, but it is not. It means a liar or someone who is a traitor. In it's worse terms it means a person who has sealed his soul with an demonic entity, hence why the name was labeled onto male witches (or wizards) during the 14th century in Europe, as a form of disgrace. I hope that helps you.
