词源记忆法
拆
pro=pre-前(比如preview预习；preface前言)，公开+-fess-表白（confess坦白、承认）+-ion名词词尾。
记
往前面，向前一步坦白、承认，引申为共开表示、表白。
词源接说法
当然，向前一步，在公众坦白、表白，也不一定完全指的是男女朋友的表白，也可以引申为在公众发表讲话或见解或者展示技能，于是可以引申为你的一种专业技能和职业。所以profession还有专业、技能、职业的意思。
再加上al形容词后缀，表示很专业的，很职业的。
如果加上表示人的职业和性质的后缀or，变为professor，则表示非常专业和职业的人，然后又要经常说话和发表j见解的这种人，就是：教授，（大学）的讲师。
