Emoji (Japanese: 絵文字えもじ, English: /ɪˈmoʊdʒi/; Japanese: [emodʑi]; singular emoji, plural emoji or emojis) are ideograms and smileys used in electronic messages and web pages. Emoji are used much like emoticons and exist in various genres, including facial expressions, common objects, places and types of weather, and animals. Originally meaning pictograph, the word emoji comes from Japanese e (絵, "picture") + moji (文字, "character"). The resemblance to the English words emotion and emoticon is purely coincidental.
Originating on Japanese mobile phones in the late 1990s, emoji have become increasingly popular worldwide since their international inclusion in Apple's iPhone in 2011, which was followed by similar adoption in Android and other mobile operating systems. In 2015, Oxford Dictionaries named an emoji the Word of the Year.
