平凡的反义词是伟大 普通的反义词是特别

我认为，普通，强调自己的各方面和大部分周围的人一样。平凡，是说明不具备很出众的特点。

普通 = ordinary 平凡 = without extraordinary powers; blah. The subtle difference is almost like being "ordinary" vs "normal".

Ahthough It's not difficult at all for native Chinese speakers: when to use 普通 and when 平凡, it may be a big headache for CSL learners. When it comes to the subtle differences in meaning and use, I'd say, roughly: 1. 普通is more commonly used and 平凡 is more literary. 2. 普通is neutral and 平凡is often used with an approving tone. 3. PAINFUL COMPLICATION, THE COLLOCATION AND THE CONTEXT: for example: 我只是个普通人 ✔ 我只是个普通的人(formal or literary, unnatural in daily language) 我只是个平凡人（？，at least feeling unnatural）, 我只是个平凡的人 ✔ （literary） 。。。。。。 The best and most efficient, reliable way to figer it out is YOU FIND IT ON YOURSELF: SEARCH IN CORPRA for Chinese language AND FIND AS MORE AS POSSIBLE USAGES of 普通and 平凡. Read and compare and you'll gradually make out what the underlying meaning-diffences ever are. ( corpara for Chinese language are fewer and poorer presently than english ones, but you can use them in Chinese learning, still.) Enormous actual usages: this is the way how everyone learns his/ native language and why a foreign learner, if not immersed in it for a long time, can hardly speak it as good as a native.

“普通”和“平凡”在意思上差不多，但是在用法和搭配上有些不同。“普通”可以说人，也可以说东西。比如“我父母都是普通人。”，在这儿“普通”有一般、不特别的意思。“普通”还可以说东西，比如“他开的车很普通”。 而“平凡”可以说”平凡的工作“，”平凡的人“，换用”普通”也可以。 但是在下面这个句子”他是我的普通朋友，不是男朋友“中，普通不能换成平凡，因为这里普通有不特殊的意思。
