"A large amount of data have to be analyzed by medical experts, if a pathology is unknown in advance"
In the sentence I've used the word "pathology" in the meaning of a quite serious disorder when something is wrong with an organ or some part of a person's body. For instance, if a person was born with a diseased liver, he is said to have a liver pathology. Am I using the word "pathology" correctly in my examples?
I'm asking because "pathology" also has another meaning as a science studying various disorders in a human body and actually there're many more links on the Internet for this meaning than for the meaning I' was wondering about.
Do you mean unknown (to medical science) or undiagnosed? The word 'pathology' suggests the former.
There still exist people who insist the the word 'data' is plural; and you may be one of them. That's fine - but an amount of anything is singular.
Right, I'm one of those who think that "data" is plural because "datum" is singular. In formal technical writing I encounter both forms of auxiliary verbs with data. Concerning "amount", I know, of course, that it's singular, but here I thought that we had to use "have" because of "data". Anyway, I've realized my mistake now.
Regarding my question, I actually mean neither unknown nor undiagnosed. Of course, a pathology can be either, but doesn't have to be so, I think. Saying a pathology, I just mean a condition when there're some organic problems with an organ: for example, a person's liver is damaged because of intense alchologol consumption or a person's heart is bad because of smoking. Pathology is a condition, as far as I understand. This condition can be treated by conservative methods, but sometimes requires surgery.
