In comics, words are usually held inside shapes. The shapes are called bubbles, balloons, and sometimes boxes. The type of shape is like a code that tells who is saying the words and how they are doing it.
Talking and thinking by a character are in balloons and bubbles, while boxes usually hold words from a narrator or background information.
