I'm afraid I have to disagree with Zooey on this one. Mounting is a perfectly normal word, and is not exactly the same as rising or increasing. When something "mounts up" it means that it is increasing at a rate that doesn't allow enough time to resolve the previous issue.... hopefully these examples will make it clearer: I have an increased workload since I was promoted, but I can handle it. I have an increased workload since I was promoted, it's too much. Reports just keep mounting on my desk! Feel free to use mounting in this way. I don't think you need to change it. @ DanO, yep, you're right mate. Think I went to far to the other end of the scale to make my point. I would definately agree that it doesn't have to imply "can't keep up", "it just means it's difficult to keep up" cheers

Hmmm...I'm going to take the middle ground here. First of all, "mounting" in this sense would rarely be used in oral English (except during a presentation). "Mounting demand" is much more common in written English. I've never used "mounting" in this sense orally in my entire life! In addition, "mounting demand" does not imply that demand is increasing at a rate that can't be satisfied; it implies that demand is increasing at a rate that is difficult to satisfy or will require extra effort. Therefore, "mounting demand" does, indeed, mean "increasing" or "rising" demand, but perhaps more accurately, it means "a sudden rapidly increasing demand."

It means increasing demand. This is a strange old use of the word 'mount', we don't use it very often except I suppose to mount a horse, or to talk about something rising up... like mounting demand! I would not prefer that word choice though, 'rising' or 'increasing' is a clearer way to say the same thing. 'Mounting demand' makes the words sound a little stuffy or artificial. It sounds like ad copy but not something a real person would say.
