    The Patronus Charms Is One Of The Most Ancient Charms In Existence

    From Redditor u/ibid-11962:

    [Rowling said] The Patronus Charm is one of the most ancient of charms and appears in many accounts of early magic. In spite of a long association with those fighting for lofty or noble causes (those able to produce corporeal Patronuses were often elected to high office within the Wizengamot and Ministry of Magic), the Patronus is not unknown among Dark wizards.

    The Patronus Charm Is The Most Famous Defensive Charm In The Wizarding World

    From Redditor u/ibid-11962:

    [Rowling said] The Patronus is the most famous (and famously difficult) defensive charm. The aim is to produce a silvery-white guardian or protector, which takes the form of an animal. The exact form of the Patronus will not be apparent until the spell has been successfully cast. One of the most powerful defensive charms known to wizardkind, the Patronus can also be used as a messenger between wizards. As a pure, protective magical concentration of happiness and hope (the recollection of a single talisman memory is essential in its creation) it is the only spell effective against Dementors. The majority of witches and wizards are unable to produce Patronuses and to do so is generally considered a mark of superior magical ability.

    Extinct Patronuses Are Very Rare

    From Redditor u/ibid-11962:

    [Rowling said] Extinct Patronuses are very rare but not unknown. Strangely, given their long connection with wizardkind, owl Patronuses are unusual. Most uncommon of all possible Patronuses are magical creatures such as dragons, Thestrals and phoenixes.

    Dogs, Cats, And Horses Are The Most Common Patronuses

    From Redditor u/ibid-11962:

    [Rowling said] It is usual, but not inevitable, for a Patronus to take the form of an animal commonly found in the caster’s native country. Given their long affinity with humans it is perhaps unsurprising that among the most common Patronuses (although it must be remembered that any corporeal Patronus is highly unusual) are dogs, cats and horses. However, every Patronus is as unique as its creator and even identical twins have been known to produce very different Patronuses.

    Most Witches And Wizards Cannot Produce A Full Patronus Because They've Never Encountered A Dementor

    From Redditor u/Mattpartridge24:

    Most adult wizards cannot produce a patronus because they never needed to learn, because the vast majority never come in contact with dementors. It is difficult magic, but most skilled adults could learn it, they just never need to. It's also clear that only Order of the Phoenix members are really aware of how to use them for communication. It's not surprising most people don't use them for this as they're not the most reliable method, once you send them you have no way of knowing who else might hear them or whether they reached the intended person. All the instances we see them used for communication in the books, it's for an emergency. Where speed is more important than security.
