Riddle: We are five little objects of an everyday sort. You will find us all in a tennis court. What are we?
Thinking about the answer of this riddle, many different objects -such as a tennis ball, a racket- might visit your mind. However, there are two reasons why these assumptions are not plausible.
Firstly, the things we need to find are five little objects that we use every day. Secondly, these objects that come to your mind are solid, but we need to think about abstract things as well. With these in mind you can figure out that the things that are five little objects of an everyday sort and all can be found in a tennis court are vowels. ( A tEnnIs cOUrt)
The answer is: Vowels.
