Question: I have a system which has the following structure:

Inbound > Open > Pending > Awaiting reply > Ready > Closed

I'd like to use single-words, so the one that sticks out like a sore thumb is "Awaiting reply".

I obviously can't use "Pending" because that's already in use. And "Awaiting" is too similar to "Pending".

Is there a word for "waiting for a reply"?

Answer: 
I don't think there is a single word for *waiting for a reply*. One can expect, anticipate, await, envisage, assume, etc, but they all would need *for a reply*.

One can be [expectant](http://www.thefreedictionary.com/expectant) or expecting, but be aware that this word is commonly used for pregnant. One can also be *anticipant*, *anticipative*, *ready*, and *hopeful*, but I'm unsure these will meet your needs.

Expectant has a noble lineage.
