Do you have any words in your conlang that are onomatopoeic or mimetic in origin? I'm talking less about actual sounds (such as "boo-hoo" or "woof") but actual inflected (if it applies) nouns and verbs that derive from sounds.
I was reading about the Latin word for owl, būbō (Ital. gufo) that ultimately derives from a PIE root imitating the sound the owl makes.
The Halvian word for dog, árvos, is derived from the English onomatopoeia "arf, arf".
The Halvian word púnsis, meaning "strike" is derived from the sound of doing so (the onomatopoeia "pow!" comes to mind). The word blāma, meaning "cry" or "call" (as in, one that calls together a gathering), is derived from the sound of a trumpet or horn. The verb dínise means to "ring". Guess where that one came from. There is also a Halvian drum called a baúmbos, which clearly derives from its sound.
That's all I can think of at the moment. What onomatopoeic words do you have?
