Verbal crutches refer to filler words like "hmm", "uh", and "ah" that people use between words when trying to form their thoughts. They can also be words like "like", "basically", and "actually" that are used repeatedly. Using verbal crutches shows a lack of confidence and continuity in thinking, and it may indicate a lack of knowledge or lying. To reduce verbal crutches, people should speak more slowly to match their thinking rate, pause when they have nothing to say, and learn to punctuate speech with pauses between groups of words conveying an idea. Practicing these techniques can help remove verbal crutches.
