I recently discovered that proper use of emojis is part fact, part fiction, and always subject to interpretation by senders and receivers. I dug into my keyboard to search the original meanings of various emojis and how they are actually used by most people. That's when I stumbled on the Emoji Dictionary! The "definitions' are user-generated, so it's interesting to read what people think they mean, and how they are used. Another fun source for emoji translations is Emojipedia. For example, did you know this?

🍆 Aubergine

An eggplant emoji, known as an aubergine in Japan and some other countries speaking British English. A long, purple-looking vegetable used in many types of cooking around the world. It is considered lucky in Japan to dream of an eggplant in the first dream of the new year.

The hashtag featuring a single eggplant / aubergine emoji #🍆 cannot be used to view photos using Instagram's emoji search function, due to common usage as a phallic symbol.
