👉 The def fluid, also known as defluid or defluency, is a term used to describe the phenomenon where a person interrupts their own speech or stutters, often by repeating a word, syllable, or sound, or by inserting an incorrect word into their sentence. This disruption can occur in various contexts, from casual conversation to formal speeches, and is often perceived as a sign of difficulty in speech production. Defluency can be caused by several factors, including nervousness, anxiety, or a lack of fluency in language, and while it can be embarrassing for the speaker, it is a common and natural part of human communication. Understanding and managing defluency is important in both personal and professional settings to improve clarity and confidence in speaking.
