When does a lawyer need a linguist?
More basically, what is a linguist?
There are many different kinds, dozens of areas of emphasis. Ultimately one becomes one’s own kind of linguist, depending on where one’s interest and preferences lead.
I’m always interested in real data – not interested in voguishly Chomskian sterile theorizing. My honors thesis was a study of African-American dialect in the fiction of Richard Wright, James Baldwin, Ralph Ellison, and others.
My doctoral thesis was an analysis of actual speech data (Hawaiian English), recorded, as spontaneous as it could be with an observer present. The social sciences are a clear case of observer influence – you don’t have to resort to quantum physics to see it.
