How is PLZ used in a sentence?

[Vinithra Karunanidhi]

PLZ is usually placed before or after a request. For example, "PLZ help me with this," "Can you call me back, PLZ?" or "PLZ don't forget my book." It is most appropriate in informal communication with friends, classmates, or online contacts. In professional emails, school assignments, or formal messages, writing the complete word "please" is usually a better choice.
