Comes in the mail word stack

A Word Stack!

Here's how it works:

1. I'll think of a word and write it on a "stack" of words.
2. You'll receive a set of letters, and your task is to unscramble them to form a word that is related to the original word on the stack.
3. When you think you have the correct answer, type it in, and I'll let you know if you're correct or not.
4. If you're correct, I'll give you another set of letters to unscramble, and so on.
5. If you're incorrect, I'll give you a hint to help you solve the puzzle.

Ready to start? Here's your first set of letters:

A E L M O R T

Unscramble these letters to form a word that is related to the original word on the stack. Good luck!
