Tā de huà xiàng yīgè yǎmí, ràng rén mōbuzháo tóunǎo.
His words were like a riddle — no one could make sense of them.
Tips
usage
The locked-in collocation is 打哑谜 (dǎ yǎmí, 'play a riddle / talk in riddles') — used when you accuse someone of being deliberately cryptic instead of speaking plainly. Literally 'mute riddle': a message wrapped so silently you have to crack it yourself.
memory
哑 means 'mute/silent' — the riddle 'speaks' without saying anything directly, like the way 哑剧 (yǎjù, 'mime') tells a story without words. Combine with 谜 'riddle' and you get a riddle that withholds its real subject.
