Let’s get onomatopoetic. We got cause of the sound, english word for it and finally its finnish counterpart.

Sneeze: Achoo – Ätsihh.
Lion: Roar – Mur.
Snoring: Zzz – Krooh pyyh.
Cow: Moo – Ammuu.
Water: Drip drop – Tip tip.
Crash: Boom – Pum.
Fart: Poot – Prööt.

Those are some of the common ones. But how do you english speakers write “buu-du”? You know, the thing baritone saxophone constantly plays in THREE MAGIC SLIPPERS?
