It's Friday again, how about some fun to get us into the weekend?

What is the longest word you can come up with for which all the letters in that word are in alphabetical order? 

Rules:

* English words only
* Can't be a name of a place, person or other proper noun.
* if it contains the same letter twice in a row, that does not disqualify it.
* No fair looking it up on Google!

Update: One more rule to help you guys out.

* The word can be in either ascending or descending alphabetical order.
