Looking for meaning in the sounds around them, the first generation of Adamics will turn first to onomatopoeia words.
Here are some onomatopoetic words based on human noises
crying=wai-wai / feeling sudden pain=wai
food being eaten= ama-ama / biting=ama
heart beating=tuka-tuka
laughing=aha-aha / surprising someone=aha
swallowing=uku-uku
breathing=uhu-uhu / Doing nothing (pausing)=uhu
sneezing=aku
yawning=ua
Mechanical noises
dripping=kuwu-kuwu / losing something=kuwu
running=taka-taka / knocking=taka
walking=tupu-tupu / striking s.th. soft=tupu
motor running=humu-humu
rolling= poto-poto falling onto something=poto
striking something wet=pata
switch engaging=kiti
Other things will make no noise, but nonetheless will be assigned mimetic words, words that sound like the way an object or action would sound if it made a sound.
Sparkling=pina-pina / Lights coming on=pina
Sparking (electricity)=piti
Note that reduplicating words makes the actions they describe long or repeated.
