In this article, we will share a list of Japanese words that are or can sound childish when spoken by adults. Generally, children learn these variations, simplifications, or attempts to say a certain word.
The fact that the word is considered childish does not mean that adults can speak them. In fact, many of the words in this article are also pronounced by adults, they just give the idea of being a little childish.
Other words that will not be listed and generally are part of a child vocabulary are the onomatopeias. I hope you enjoy the list of words in this article. We appreciate the comments and shares. xD
