• appraisal 本词

  A more formal, often professional judgment of the value or quality of something, made after careful assessment; common in contexts like job performance reviews or property valuation.

Both estimate and appraisal are judgments people make about something. Estimate is a quick, rough guess about amount or cost, often casual. Appraisal is a more formal, careful judgment of value or quality, often professional.

这两个词都指对事物做出的判断，但estimate侧重快速、粗略的数量或费用估算，语气较随意；appraisal强调更正式、经过仔细评估的价值或质量判断，常见于专业场合。此处只比较所给的这一义项。
