The correct spelling is actually "have confidence in", not "have confidence of". The preposition "of" is not used after "confident" in English. This mistake may be due to confusion with the phrase "be certain of". The correct pronunciation of "confidence" is /ˈkɒnfɪdəns/ (KON-fi-dəns) with the stress on the first syllable. "In" is pronounced /ɪn/ (in) with a short "i" sound followed by the nasal consonant "n".
The phrase "have confidence of" typically refers to the state of having assurance, belief, or trust in someone or something. It implies a strong sense of reliance and certainty in a particular person, group, or situation. When someone says they "have confidence of" someone or something, it implies that they have faith in their abilities, judgement, or reliability, often based on previous experiences or knowledge.
Having confidence of someone can mean that you trust them to fulfill a certain role, meet expectations, or carry out specific tasks. It indicates that you believe they possess the necessary skills, knowledge, or qualities to succeed in their endeavors.
Alternatively, having confidence of something can mean having belief or trust in the validity, accuracy, or effectiveness of that particular thing. It suggests that you rely on it as a source of information, a tool, or a solution. This confidence could be based on personal experience, reputation, or established credibility.
In summary, "having confidence of" encompasses having a strong belief or trust in someone's abilities or in the reliability and effectiveness of something, demonstrating a sense of reliance, assurance, and certainty.
