It sounds like some people here have issues with word-retrieval, but I wouldn't go so far as to call it aphasia.

Nominal aphasia (anomia) is a type of aphasia characterized by problems recalling words or names. Subjects often use circumlocutions (speaking in a roundabout way) in order to express a certain word for which they cannot remember the name. Sometimes the subject can recall the name when given clues. Sufferers are often frustrated when they know that they know the name, but cannot produce it.
As I have said, it varies in severity. If I had to diagnose people, I would say that the girl in the OP has nominal aphasia. I myself probably have Conduction aphasia, and maybe a mild case of nominal aphasia. I would venture a guess that many non-verbal people here like Age1600 have Broca's aphasia. At least based on what she has written. People who use a lot of echolalia probably have Transcortical motor aphasia. I of course cant diagnose anybody over the internet, but the OP definitely sounds like nominal aphasia to me.
