Confidence is a trait that is highly valued in professional, personal and social settings. However, when it comes to communication, using the same word repeatedly can get a bit boring. Therefore, it is always essential to have synonyms ready that convey the same meaning, but with a slight difference in connotation. Words such as self-assurance, self-confidence, poise, courage, assertiveness, and composure can be used instead of confidentness. These words not only add variety to your communication but also give you a chance to broaden your vocabulary. In conclusion, having a range of synonyms for the term confidence can boost confidence in yourself as a writer, speaker, or communicator.
