If we read the literature regarding Wizards there are very few who get married.  Same for Witches.  It seems Wizarding and Witching are essentially solitary occupations.

There is no Mrs. Gandalf, no Mrs. Saruman calling up Mrs. Sauron on the Palantir to discuss her husbands plans for world domination. There's no Mrs. Wizard-of-Oz, no Mrs. Merlin.  Even Harry Potter seems destined to remain single at his current rate of progress with the opposite sex.

Witches also generally remain out of wedlock - although they sometimes come in threes like Shakespeare's Weird Sisters and the Three Fates - but these trio's are also almost always unwed.  There's no Mr. Jadis pottering around the garden shed while the White Witch is in the kitchen brewing up more Turkish Delights. It's just Baba Yaga, not Mr. and Mrs.Yaga.  We know a great deal about the Discworlds Granny Weatherwax but there is no mention of Grandfather Weatherwax.

Sure there are probably exceptions. In a Universe founded on Quantum Indeterminacy and Probability it's a rule that there are always exceptions to every rule (including this rule, which is why we have Death and Taxes!).  But in general it's fairly safe to say there are usually no Mrs. Wizards and no Mr. Witches.

Which brings us to Wizitch ~ a union between two magic people, one of whom happens to be a Witch and the other a Wizard!  

Wizard + Witch = Wizitch!

Practitioners of magic know the only rule is that there are no rules and the only certainty is that there is only uncertainty - so it is that Wizitch can calmly ignore the conventions of Witching and Wizarding as it suits. It suits this Wizard and this Witch to create a unique union.

Interestingly, practitioners of magic also know that the most powerful place is always the centre, the point of balance.  Even a brief perusal of the topic of magic will soon reveal that it's all about balancing the Male (outgoing) principle with the Female (incoming) principle - the so-called Sacred Marriage, the combination of both Yin and Yang.  This is the real reason we find so few Magical characters joined in happy wedlock - to function as a Wizard a man must meld his male (thinking) characteristics with his female (feeling) characteristics.  The same principle reversed applies for Witches - women whose feelings are balanced by their thoughts.

The "secret" to a magical life has been described as the union of male and female - the conscious and the unconscious -  thinking heart and loving mind.  Folk who achieve this inner equilibrium usually do not need a partner of the opposite sex to feel complete as they already feel complete within themselves. 

So it is with Wizitch - two complete people coming together to create a sacred magical connection. This is quite different to many normal 'relationships' where two basically incomplete folk seek completion from an external source.  Wizitch does not require each other for completion - both are independently complete.  This means the connection is not based on need but on choice - we don't 'need' to be together - instead we choose togetherness.

The result is the happiest, most magical, most wonderful partnership either of us - Wizard and Witchy - have ever encountered.
