Onomatopoeia will not have an 's' in the end... While for the sound it is important to know where you want to place it... you can use stomp, tromp, or even animal sounds like meow etc....

I'd sooner say "examples of onomatopoeia". Just adding an "s" to the word looks clumsy (though wikipedia says it's OK... I disagree). The closest thing you could get to a decent plural of onomatopoeia might be "onomatopoeiae", following Greek rules of pluralisation. Just by the by... :)
