除了 point out, indicate 這兩個基礎的「指出」用字之外，本文介紹四個進階的用語供讀者更精準地表達想法，抱括：Recognize, Identify, Specify, Pinpoint
Recognize or Identify
Recognize = 認出 = to know someone or something because you have seen or heard him or her or experienced it before。關鍵字根是 re + cognize = 再一次認知。其中與 cognize 最接近的字是 cognition = 認知。所以說 recognize 真正的意思是「因為之前知道，所以再一次看到時想起來」。
Identify = 識別出 = to recognize someone or something and say or prove who or what that person or thing is。從英英解釋可看到，這個字不止要「認出」，還必需提出「證據」。在 → italky ← 論壇上有個解釋相當不錯，指出 identify 的意思「是你核對了某些要素」。例如我們可以利用 ID 卡來核對你的身份，而 ID 卡其實就是 identity card 意思是記錄了一些「身份資訊」的卡。換句話說，identify 暗指了必需「透過努力去核對資訊」以識別出狀況。
Recognize or Identify a Problem
I recognize two problems in this project.
The audit helped us identify two problems with our accounting system.
Recognize 暗指講者看過類似的問題，所以「認出」了問題。Identify 則是暗指必需透過努力去「識別」出問題。
Recognize or Identify a Solution
I recognize two solutions to this issue.
We need to identify two solutions to this issue.
recognize 暗指講者以前看過怎麼解決該問題，所以認得其中兩個。identify 則指暗指必需透過努力去找出解決方案。
