反而 vs 相反 (on the contrary)

• Pinyin: fǎn'ér / xiāngfǎn
• Formation: A ，反而 B (unexpected opposite within one flow) / A ，相反 ，B (contrasting two statements)
• Hanzi breakdown: 反 = 厂 (cliff) + 又 (hand), suggesting turning over; 相 = 木 (tree) + 目 (eye)

Meaning

Both 反而 and 相反 express contrast or opposition, but they function differently. 反而 means 'on the contrary' or 'instead' within a single sentence, indicating an unexpected opposite result. 相反 means 'on the contrary' or 'conversely' and introduces a contrasting statement, often between two separate clauses or sentences.

The key distinction is grammatical role. 反而 is an adverb that modifies the predicate within a clause, expressing that the result is the opposite of what was expected: 吃了药，反而更严重了 (After taking medicine, it actually got worse instead). It always implies surprise or irony. 相反 is typically used as a conjunction or adjective. As a conjunction, it introduces a second clause that states the opposite of the first: 她没有放弃，相反，她更努力了 (She didn't give up; on the contrary, she tried harder). Unlike 反而, 相反 does not require the contrast to be unexpected — it simply states an opposing fact. 反而 cannot stand alone between sentences the way 相反 can.

Examples

1. 吃了药以后，他反而觉得更难受了。 After taking medicine, he actually felt even worse.
2. 大家都在休息，她反而更忙了。 Everyone was resting, but she got even busier instead.
3. 我以为他会生气，相反，他很平静。 I thought he would be angry, but on the contrary, he was very calm.
