You can say this when you want to borrow something. If the person you are talking to is a close friend or a member of your family, you can simply say "KASHITE."
"Kashite kudasai." = Please lend it to me.
"Doozo." = Certainly.
Note: In the system of romanization used in this section, "ee" is not pronounced like feet. Instead, it means that the vowel sound "e" as in pet is prolonged. In the same manner, "oo" is pronounced not like shoot but as the "o" vowel, similar to pork, pronounced twice as long.
