Minecraft wiki entry for Raw_JSON_text_format, associated text: Raw text takes in an array of text objects. Each object in the list is added to the previous object. For example, /tellraw @a { "rawtext" : [ { "text":"Hello" }, { "text" : " World" } ] } outputs the same "Hello World" as the first example. Appending text can be useful to combine 2 different localized texts, or apply different colors to each word etc.
