Memory Modifying Charm
no incantation used
Sends a magical messenger to someone in the form of the caster's Patronus.
Dumbledore sent a message to Hagrid using this spell. He simply pointed his wand in the direction of Hagrid's cabin and sent the messenger without saying a word. Hagrid came directly to Dumbledore, which suggests that it is possible to retrace the messenger's path (GF28).
McGonagall cast this spell to contact the other three Heads of House just prior to the battle of Hogwarts; non-verbally, she conjured three Patronuses at once and sent them to their destinations, an impressive feat (DH30).
Meteolojinx Recanto (mee-tee-OH-lo-jinx ree-CAN-toh)
Halts a spell that is causing rain.
"meteorologia" Gr. meteorology + "jinx" + "recanto" L. to recant; to charm back, charm away
"mobilis" L. movable + "arbor" L. tree
Moves a tree (PA10).
The basic spell for moving something starts with the "Mobili-" prefix. It is up to the caster to be able to tack on the correct Latinate word for the object to be moved, in this case a tree. It seems unlikely that there is a "standard" spell for moving a tree to one side!
"mobilis" L. movable + "corpus" L. body
Moves a body.
The basic spell for moving something starts with the "Mobili-" prefix. In this case, the Latin word for "body" is tacked on the end.
Remus Lupin used this spell to levitate Snape's unconscious body for transport back to school from the Shrieking Shack (PA19). Unfortunately for Snape, Sirius Black then took over managing the levitation while Lupin covered Wormtail with his wand, and for some reason Sirius didn't seem to be very careful about keeping Snape from bumping into things (PA20).
Thought of the day: "A real friend helps you move a body."
"mors" L. death + "mordere" L. to bite
Conjures an immense glowing skull in the sky, comprised of green sparks. There is a snake coming out of the skull's mouth.
This spell is known only to Death Eaters, who send it up in the sky when they kill. The Dark Mark was seen at the Quidditch World Cup in 1994, [Y14], conjured by Barty Crouch Jr. using Harry's wand (GF9)
c.f. PROTEAN CHARM.
"muffle" Eng. to deaden a sound, making it more difficult to hear
Fills the ears of target persons near the caster with an unidentifiable buzzing, so that the caster can hold lengthy conversations without being overheard.
