At
a loss for words
The loss of the ability to use words is called aphasia. Since the mid 19th century this has been linked to damage in the brain, chiefly in two areas on the left side of the brain named after their discoverers Paul Broca and Carl Wernicke.

Doctor: Could you tell me, Mr Ford, what you’ve been doing in the hospital?
Patient:
Yes. Sure. Me go, er. uh, P.T. nine o’cot, speech ... two times ... read ...
wr ... ripe, er, rike, er, write ... practice ... getting better.
This
seems a string of content words; in other words the nouns and verbs are mostly
left but the organisation has gone along with the structure words like ‘of’,
the form of the pronouns I.
Here is a patient with Wernicke’s area damage answering a similar question:
Doctor:
What brings you to the hospital?
Patient:
Boy I’m sweating. I’m awful nervous, you know, once in a while I get caught
up, I can’t mention the tarripoi, a month ago, quite a little, I’ve done a
lot well, I impose a lot, while, on the other hand, you know what I mean, I have
to run around, look it over, trebbin and all that sort of stuff.
Here
the patient speaks fluently but doesn’t seem to connect with the question.
They may also have severe problems with the names of everyday objects. Mr Grogan
can manage book and ear but says chair for table,
knee for elbow: he calls clip
plick, and butter tubber. He seeks desperately for words; for ankle
he said ankey, no mankle, no kankle; for fork he said tonsil, teller,
tongue, fung.
Until
recently it was believed that damage to the right side of the brain did not
affect language. However the right brain handles emotions. In English right
damage can affect your ability to handle emotional aspects of language such as the
interpretation of emotion, allegedly leading to a higher divorce rate in right
damaged patients.
