World Emoji Day
The company Unicode actually creates the computer code that give us emojis, but Emojipedia is where you can learn exactly what each emoji means and how to use it. Most of us probably know and use the most popular emojis, like the classic smiley face, heart or the smiling face with tears of laughter. But if you want to grow your emoji vocabulary, you can use Emojipedia to find out new ways to speak emoji.
So, for example, go to Emojipedia and type in sick and it will give you several options. If you mean ill, as in the American English phrase I'm sick, you can use the face with a thermometer or a mask. Or maybe you mean I feel sick, like in British English to mean to vomit. Since 2017, when Unicode added the vomiting emoji, you can choose from two green faces. Or maybe you're just feeling a bit dizzy, in which case you can choose the confused, dizzy-looking face. If you wanted to talk about hospital or a medical condition, Emojipedia has also suggested a syringe or a pill. So you can see with just one real word, sick, you have a lot of emojis to choose from to explain exactly what you mean!
