Language plays an important role in critical thinking. There are four key areas of language use: word choice, ambiguity, definition, and intensity. A critical thinker must use language that meets the audience's needs and expectations by considering factors like time, place, person, and occasion. Their word choices should aim to accurately convey their intended message without ambiguity so the audience can understand without misunderstanding. They also clearly define any terms to prevent semantic barriers and use an appropriate intensity level for the audience.
