Onomatopoeia

Is this a biological name for some insect? You could be forgiven for thinking so, but it is a figure of speech!
It is the naming of a thing with the sound that is associated with it. For example, you could say 
" The chair fell over onto the carpet with a thud"

Here are some onomatopoeias that you often find in comic books! 

  Not all are so obvious, "the clickety-clack of a passenger cabin as it rolled along" may not catch your attention, but it is an onomatopoeia too! Some of them have been around for so long that we almost forget they are there!
