These words have one thing in common- okay several things- but the big takeaway I want to leave you with is that they have very straightforward definitions. The biggest mistake people make is to thing that witch, Wiccan, and pagan all mean the same thing. In fact the internet is dripping with this misconception. In actuality each word means something different. If anyone tells you otherwise- they are wrong! Don't listen to them. Run for the hills.

Witchcraft is the practice of effectively putting your intention out into the universe using a series of phrases and actions. A good act of witchcraft (spell) engages as many senses as possible. Where a practitioner of witchcraft (witch) performs an action, builds a physical representation of the desired result, and speaks their intention which leads them to hear their intention aloud. If those last two sentences confused you, don't worry about it, I'll talk more on that later. As I mentioned, an act of witchcraft is called a spell and it is based on a few concepts that deals with some complicated philosophy and scientific principles. When a practitioner of witchcraft (witch) performs a spell they are using magick- the force that makes their intentions a reality. And I didn't just misspell that word. Magick (with a k) is used by practitioners to distinguish from stage magic (no k) and magic (again no k) in the media. Again, a practitioner of witchcraft and magick is called a witch. These is a gender neutral term. Meaning a male practioner of magick or a gender neutral practitioner of magick or a female practioner of magick all would- unless they specify otherwise- be considered a witch. It's important to note that the term wizard is basically non-existent in the witchcraft community and some might actually take offense to the term warlock (it is considered to mean "oath breaker"). Anyone can become a witch. There is no initiation requirement and you don't have to be born a 'hereditary witch'.
You may identify as a witch once you feel comfortable doing so. Also, there is no religious or theological requirement to be a witch. There are atheist witches as well as witches of all faiths.

Phew, okay that was longer than I thought. Paganism is an umbrella term for all non-Abrahamic, nature based faiths. Most pagan faiths are polytheistic, meaning they worship more than one god or goddess. To say that paganism is an umbrella term means that there are many different pagan faiths some of which are reconstructions of ancient polytheism. For example, Hellenic Polytheism is a reconstruction of the ancient Greek religion. Other pagans worship far newer religions, for example Wicca, though based on ancient religions was created in the 1960s. Although Wicca is one of the largest pagan religions, it is not synonymous with paganism. Also, all pagan faiths are different and even within those paths there are varying traditions. The term traditions is used in paganism similarly to the way a Christian might say denomination- meaning a branch or sect of that faith. If you were talking about your personal journey or beliefs you would refer to 'your path'. That's just some verbage that you're going to encounter further into whatever pagan research you pursue.

Wicca is the largest pagan religion and there is this huge misconception that it means the same thing as witchcraft or that all Wiccans are witches. Wicca is a nature based duotheist (two deity) religion. Wiccans believe in a God and a Goddess. Wicca was created in the 1960s by Gerald Gardner who took a lot of inspiration from older sources. Gardner was a witch and took a lot of inspiration from witchcraft in forming Wicca. However, not all Wiccans are witches or practice magick. Furthermore, only a portion of witches are Wiccans.

I hope all of that made sense, and if not, message me and I'll clear it up. On the off chance that anyone wants to get to know me more, my tumblr is ivi-the-witch@tumblr.com. However be warned, I go over more advanced topics there. I intend to post more here tomorrow or the following day.
