The Manager described the new accountant as a man of impeccable character.

Step 1: Analyze the question You are asked to find the word closest in meaning to "impeccable" as used in the sentence: a man of impeccable character.

Step 2: Explain the concept "Impeccable" comes from the Latin im- (not) + peccare (to sin or do wrong). So it literally means "not capable of doing wrong." It describes something perfect, flawless, or without fault. In sentences, it is usually positive, e.g. "impeccable manners," "impeccable record," "impeccable English."

Step 3: Test each option

• A. serious: A person can be serious without being flawless. This is not the meaning.
• B. dangerous: This is negative, and it has nothing to do with the meaning of "impeccable."
• C. faultless: This matches the idea of having no fault or flaw. It fits perfectly: "a man of faultless character."
• D. rigid: This means stiff or inflexible, which is unrelated to the word.

Step 4: Answer The correct answer is C. faultless.

Tip: Link the root pecc- to "sin" or "fault." Think of "peccadillo" (a minor fault). Add the prefix im- (meaning "not"), and "impeccable" means "without fault." Many English words starting with im-, in-, or un- mean "not," which helps you with unfamiliar vocabulary in exams.
