please

"Alstublieft" is the standard Dutch word for "please." It is a contraction of "als het u blieft," which literally translates to "if it pleases you." The mental image is one of offering a request with a polite, deferential bow, acknowledging that you are asking for a favor from someone you may not know well or someone to whom you wish to show respect. While "alstublieft" is the formal way to say please, it is also used in many other contexts. You will hear it when handing someone an item (like "here you go"), when responding to "dank u" (as in "you're welcome"), or even to get someone's attention in a shop. For friends or family, you might use the shorter, informal version "alsjeblieft."
