reimbursement

Sometimes your company pays for things that you do. For example, your company might pay for your lunch if you're eating out with a client. If you have a company credit card, you can pay with that. But if not, you usually pay with your own money and then get reimbursed by your company. The money that you get back from your company is called a reimbursements.

Other things that you might be able to get reimbursed for include:

  • travel that you do for work
  • supplies that you buy
  • classes that you take which increase your job skills

submit a request

A "request" is a formal document that you fill out and give to a company, a school, a government agency, etc. to ask for something.

In the example above, a "reimbursement request" is a document you fill out to ask your company to pay you back.

To "submit" a request means to give or send it to the people who need to receive it. You can also use "submit" for things like:

  • homework assignments
  • applications
  • proposals
  • contest entries (like your artwork or a video you made)

(something) must be (done) by (a date)

Use "must" to tell people things that they have to do. "Must" is more formal than "have to" and is also stronger. It gives the impression that you are really serious and won't allow anyone to disobey you. Teachers, politicians, and other authority figures use it a lot. It's also common in written instructions, like in the example above. Another example is:

All visitors must present a valid photo I.D. before entering.

This is something that you might read on a sign in the lobby of an office building. It means that you have to show your license, passport, or other ID card to the guard before you can go in.

"Must" is also often used when giving deadlines. When you're doing this, use the phrase, "___ must be ___ed by ___":

All applications must be completed by November 30th.
