CHECK-IN OR CHECK IN?

I went to get my mammogram this week (hope if you need one that you got yours this month, too, or whenever it is due). While at the 119 Health Center, I noticed this card sitting on the desk:


Please check-in at the front desk.


Whoever created this card forgot that "check-in" should be used as a NOUN or an ADJECTIVE. In the VERB slot, as in the sentence above, the hyphen is omitted. This sentence should read as follows:


Please check in at the front desk.


Below are some examples of how to use "check-in" correctly:


The check-in desk (ADJECTIVE) is located in the lobby.


After check-in (NOUN), the plenary session will be in the auditorium.


While you are here in the blog, why not click on the "compound words" site in the index on the right and see the other compound word problems I've come across.


Have a great day!
