The structure 纵然…也… forms subordinate complex sentences and indicates that some result happened despite circumstances that may make the result seem unlikely.
For example: “even though he did wrong, we still remain friends”.
In the first part, after 纵然, we state a possible or existing circumstance. In the second part, after 也, we state the result that won't change despite the stated circumstance.
Scheme
纵然
circumstance
也
unchangeable result
Pay attention
We can state the subject either before 纵然 or before 也.
Examples
纵然时间消逝,我也不会忘记你
Even if a long time passes, I will never forget you
zòngrán shíjiān xiāoshì, wǒ yě bú huì wàngjì nǐ
他们的想法纵然不一样,也要互相支持
Even though their ideas are not the same, they have to support each other
tāmen de xiǎngfǎ zòngrán bù yíyàng, yě yào hùxiāng zhīchí
他的行为纵然不好,也是他们之间的事,我们不要管了
Even if his behavior is not good, it is still their problem. It doesn’t concern us
tā de xíngwéi zòngrán bù hǎo, yěshì tāmen zhī jiān de shì, wǒmen bú yào guǎn le
Pay attention
Usually there is a negation in one part of the sentence.
Sometimes 纵然 can be replaced by 纵使 in the structure.
Examples
纵使明天下雨,他们也要去游览
Even if it rains tomorrow, they are going on the excursion
zòngshǐ míngtiān xià yǔ, tāmen yě yào qù yóulǎn
纵使今天的结果不是零,将来也会是零的
Even if the result is not zero today, it will still be zero in the future
