半天
Despite literally meaning 'half a day,' 半天 in spoken Chinese means 'a long time' or 'forever' — usually with mild frustration or surprise. 'I waited forever.' 'It took me ages to figure out.' '说了半天' (talked for ages). Pure colloquial register, very common in everyday speech. It's not measured time — it's the speaker's feeling that something took longer than it should have.

How to Think About It
Native speakers feel 半天 the same way English speakers feel 'forever' in 'I waited forever' — exaggerated, emotional, never literal. The clue is context: if someone says '我等了半天' at 9:05 AM after waiting since 9:00, they don't mean 'half a day' — they mean 'longer than I wanted to.' 半天 usually carries a tinge of annoyance, surprise, or vain effort. Pair with 才 ('finally') or 也没/都没 ('still didn't') to emphasize the wasted-effort flavor.
Examples
我等了半天, 他才回我消息。
Wǒ děng le bàntiān, tā cái huí wǒ xiāoxi.
I waited forever before he finally replied.
想了半天也没想起来他叫什么。
Xiǎng le bàntiān yě méi xiǎng qǐlái tā jiào shénme.
I thought about it forever and still couldn't remember his name.
你说了半天, 我都没听懂。
Nǐ shuō le bàntiān, wǒ dōu méi tīng dǒng.
You've been talking forever and I still don't get it.
Common Mistake
Learners take 半天 literally and translate it as 'half a day' or 'twelve hours,' producing odd sentences. In conversation, 半天 almost never means a real duration — it means 'an annoyingly long time.'
我等了半天, 大概十二个小时。
我等了半天他才来。
Don't Confuse With
很久
很久 is neutral 'a long time,' no emotional color — works in formal and casual contexts. 半天 always carries some frustration or vain-effort feeling, and lives in spoken language.
一会儿
Opposite duration — '一会儿' is 'a moment / a little while.' Use 一会儿 for short waits, 半天 for waits that felt too long.
老半天
Intensified version: 'forever and ever.' 老 adds extra emphasis — '我找了老半天' (I searched forever). Same flavor as 半天 but turned up.
