Telekinesis

Telekinesis is a form of magic that involves using the mind to move and manipulate objects and humans. Although in the show it has never been mentioned by this name, this kind of power represents one of the most basic aspects of sorcery (like the ability of casting spells). People who have aptitude for magic can gain this skill through practice and study; there are also some extremely gifted warlocks and witches, like Merlin, who can move and manipulate objects instinctively since they're very little.

It's not clear if this form of magic is performed only by casting spells (sometimes non-verbally, enchanting a spell in the mind) or also without an incantation. This probably depends on the sorcerer's power, with the most powerful ones who don't need to pronounce a formula.

Some kinds of spells, like stunning spells, could be related to this power. Anyway, Stunning Spells in particular are more likely to be elemental spells linked to Air, for when they're cast, the sorcerer creates a very powerful air current that strikes his opponent.

This power can be divided into three categories: spells that push objects, spells that move them and spells that make them fly (the most common).

Verbal telekinesis
Merlin and other sorcerers have used this form of magic countless times, mostly non-verbally. Along with a spell it has been used in these occasions:
 * Onhríne achtung bregdan, used by Merlin to open the etiquette book and study the different parts of a knight's armour. Gaius reproached him for this, because he didn't want Merlin to use his magic too much (Valiant).
 * Feormian dust rénian, used by Edwin to put the blue sand, that Merlin had accidentally dropped, back in its bottle. He wanted to show Merlin his powers and that he was skilled in the words of power of the Old Religion (A Remedy to Cure All Ills).
 * Rǽdee ásce geotan, used by Merlin to levitate the bottle and pour the sand in a bowl, to show Edwin that he too knew how to cast spells in the language of the Old Religion (A Remedy to Cure All Ills).
 * Swilte Merlin, used by Edwin to try to throw an ax against Merlin. He had the ax levitate non-verbally, but Merlin was able to stop it with his mind. Edwin tried to intensify his spell using this incantation, but Merlin was strong enough to send the ax back against the warlock (A Remedy to Cure All Ills).
 * Onbregdan, used by Merlin to summon Sophia's Sidhe Staff, that Aulfric's daughter had left unguarded on the shore of the Lake of Avalon (The Gates of Avalon).
 * Bestepe scós. Gestælle scós. Astýre scós, used by Merlin to move, stop and then move again Mordred's boots. When Arthur started searching Morgana's rooms for the druid boy, Merlin noticed that he had left the boy's boots in plain sight, so he hid them by making them walk behind the screen (The Beginning of the End).
 * Inbringe cume mec, used by Merlin to levitate Arthur's keys. When the Prince heard the keys' clanging sound, Merlin made them fly over and behind his head, so that he couldn't see them (The Beginning of the End).
 * Fleoge, used by Merlin to make Arthur's sword fly against the Questing Beast. After having made the sword fly, the young warlock cast on it the enchantment to strengthen mortal weapons (Le Morte d'Arthur).
 * Astyre, used by Merlin to make the boat he used to go to the Isle of the Blessed move (Le Morte d'Arthur).
 * Flíe fǽgð, used by Merlin to shoot a spear against the wild boar. He did this while hiding behind a tree, and as he couldn't reveal his magic, Cedric got the credit for killing the boar (The Curse of Cornelius Sigan).
 * Onbinde þa téage, used by the young warlock to break Myror's horse's saddle strap. In the episode "Gwaine", Merlin did the same thing to save Arthur, but this time he didn't chant the spell aloud, but conjured it non-verbally (The Once and Future  Queen).
 * Gestillan, used by Merlin to stop various objects, including a broom, that he'd accidentally pushed over in order not to wake Gaius up. Merlin displayed a certain ability by being able to control several objects at once (The Nightmare Begins).
 * Binne tófléon, used by Emrys to push numerous barrels around and distract the guards at the entrance of the Citadel (Lancelot and Guinevere).

 * Scéawere, folge min bebod, used by Merlin to levitate a mirror out of Arthur's window and see the reflection of Lady Catrina's true face, whose room was exactly one floor below Arthur's. Merlin lost control over the mirror when he saw the troll's face, making it fall down and thus waking the Prince up (Beauty and the Beast).
 * Flíeh hrǽgl, by Merlin to pull the rug from underneath Catrina, so that Arthur could easily stab her with his sword (Beauty and the Beast: Part Two).

 * Ic bebíede þis giestærn tácen fielan, by Merlin to make the inn's sign fall on Halig when the bounty hunter realised that Freya had been freed (The Lady of the Lake).

 * Flíeh hrǽgl, used by Trickler to push the carpet from underneath Gwen. The servant fell and Trickler was able to bring Vivian breakfast in her place (Sweet Dreams).
 * Fluge! Gár, used by Merlin to throw a spear against the Great Dragon. This spell had the same effect of an enchantment to strengthen mortal weapons, possibly indicating that Merlin partially conjured it in his mind (The Last Dragonlord).

 * Cæga cume her, used by Merlin to levitate the cell door's keys. He had been arrested for sorcery but he escaped by summoning the keys (Goblin's Gold).
