Common mistakesConfusing 'expert' with 'experienced' — an expert knows a lot, while an experienced person has done something many times., Using 'expert' without specifying the field, which makes it vague., Incorrectly pronouncing it as 'ex-pert' instead of 'ek-spurt'.Confused with 'mastery' which is the state of being skilled., Using 'master' inappropriately as a verb without context., Assuming 'master' must refer to a male.
Usage notesUse 'expert' to describe someone's high skill or knowledge in a specific area.
