Let’s clear one thing up first-there are emojis and emoticons. The latter are little images which are made using normal keys on a keyboard.

But as technology has improved, many images have been created and they can be simply a____82____ to your messages, which is great! The emoji was first invented in Japan in the late 1990s and the word “emoji” comes from the Japanese words for “picture” and “character”. The number of different images has greatly i____83____since then. Now we have a picture of every mood or situation. Another a____84____of emojis is that they are an international language-they don’t use word but tell a message in pictorial form so they can be e____85____ translated whatever your native language is.
