e is a lowercase vowel, which is the 5th letter in the Latin alphabet. Known as "yellow" or "light yellow" by those who have grapheme-color synthesia, surprisingly different from E, which is perceived as "light green". e is also crucial in mathematics for the irrational number, approximately equal to 2.71828... used in euler's identity and many other formulae. The choice of the letter is believed to be because it was an unused letter after A, B, C, which are commonly used in set theory to
define sets.
In internet culture, "e" is often used as a reaction, originating from the "
markiplier E" or also known as "lord marquaad E"
meme from the "Deep Fried
Memes" series.
