准儿

tā dào dǐ lái bù lai yī zhí dōu méi yǒu zhǔn r

他到底来不来，一直都没有准儿。

We are not sure yet whether he will come.

xīn lǐ yǒu zhǔn r

心里有准儿

feel sure

zhè shì chéng bù chéng dōu méi zhǔn r

这事成不成都没准儿。

The chances of success are uncertain.

nǐ jǐ diǎn zhōng kāi gōng hái méi zhǔn r ne

“你几点钟开工？”“还没准儿呢。”

“What time do you start work?” “It varies.”

zài zhè me dài xià qu méi zhǔn r lián wǒ yě huì mí lù le

再这么待下去，没准儿连我也会迷路了。

If we stay here any longer, even I might lose my way.
