What are all of the Harry Potter spells and their meanings?

The Harry Potter books are full of spells that are learned and used by the various characters. The spells were all invented by J.K Rowling, though many of their roots are related to Latin and English. Here are five of the most important spells used in the series with their meanings and some context for when they were used:


Alohamora-this spell is used to unlock doors. Hermione was the first to use it in the first book of the series when she, Ron, and Harry were sneaking around Hogwarts.


Wingardium leviosa-this is a levitation spell, to make things float and fly. Professor Flitwick teaches it to the class, which includes Hermione, Ron, Harry, Neville, and the other Gryffindors. Their first task is to make a feather levitate. Hermione is the only successful one at first; she says it's because the others are pronouncing it incorrectly.


Expelliarmus-this spell is used to disarm one's opponent and take away their wand. It is a fairly simple spell, but it gains fame because Harry uses it on multiple occasions, most famously to defeat Voldemort.


Lumos-this spell causes the end of one's wand to light up. It is a spell they learn early on and then use throughout the books to light their way in the dark.


Accio-when a witch or wizard says "Accio" followed by the thing they want, that thing comes to them. For example, Harry says "Accio broom" to summon his broom from another location in the fourth book.


By just skimming through the books you could find countless more, but these five are very important.

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

A man has a garden measuring 84 meters by 56 meters. He divides it into the minimum number of square plots. What is the length of the square plots?

We wish to divide this man's garden into the minimum number of square plots possible. A square has all four sides with the same length.Our garden is a rectangle, so the answer is clearly not 1 square plot. If we choose the wrong length for our squares, we may end up with missing holes or we may not be able to fit our squares inside the garden. So we have 84 meters in one direction and 56 meters in the other direction. When we start dividing the garden in square plots, we are "filling" those lengths in their respective directions. At each direction, there must be an integer number of squares (otherwise, we get holes or we leave the garden), so that all the square plots fill up the garden nicely. Thus, our job here is to find the greatest common divisor of 84 and 56. For this, we prime factor both of them: `56 = 2*2*2*7` `84 = 2*2*3*7` We can see that the prime factors and multiplicities in common are `2*2*7 = 28` . This is the desired length of the square plots. If you wi...
