Excerpt from this article:
The oldest written language in the world didn’t have an alphabet. When written language began, it wasn’t used to ‘sound out’ words the way many writing systems do today; instead, each symbol represented a word (or occasionally part of a word). If that sounds familiar to you, it’s probably because speaking with pictures is a familiar concept — modern Chinese (hanzi) is a kind of logographic writing system, as is Japanese kanji. Younger readers, of course, may jump to an even more modern example of a logographic writing system — stickers.
There has been a lot of ink spilled about how stickers and emoji are bringing about the death of modern communication, but that draws an incorrect (and Western-biased, and frankly kind of racist) parallel: that language evolved from a logographic language (hieroglyphics, say) into an alphabetic language (English). In point of fact, English didn’t evolve from a logographic system at all; it’s a cousin, not a child. And Mandarin, whose billion active speakers make it the single most spoken language in the world, uses a syllable-based logographic language system.
Now, linguists may object to the classification of emoji as a logographic writing system.
