Apostrophe (glottal stop) is very important in our language, and other languages around us. We must use it to spell names and words correctly. Examples:

sulu = a young animal (deer, etc.)
suluk = to hide
sulu' = a torch made from tree sap

bulu = hair (like the fine hair on one's forearm)
bulu' = a type of bamboo

ue = water
ue' = rattan

bolo' = a hole; a pothole in a road
bolok = rectum

Please allow the apostrophe to be used for usernames! Thank you!
