毕竟【bìjìng】

毕竟 brings in a fact that can't be argued with and that explains or excuses something. It goes after the subject or at the start of its clause.

A common shape gives a judgement or a request first, then 毕竟 with the reason behind it.

With a concession

With 虽然 or 但是, 毕竟 says that whatever the drawbacks, the basic fact still holds.

Not "after all" as in "in the end"

English "after all" also means a plan changed: "I went after all". That is 最后还是 or 还是. And "finally", after a long wait, is 终于.

• × 我本来不想去，毕竟去了 → 我本来不想去，最后还是去了
• × 我们等了很久，他毕竟来了 → 我们等了很久，他终于来了
