mightn't meaning in Chinese
mightn't ＝ might not.
Examples
- We mightn't be so lucky this time .
这一次我们的运气可能不会那样好。 - She mightn't be inhaled as a rose, but she might be grasped as a nettle .
她不是一朵香气扑鼻的玫瑰花，但至少是可以握在手里的荨麻。 - It was too bright and bouncy, too big sister, though it mightn't strike an old person .
这句话说得过于动听，说得过了头，太主观武断了，好在这还不至于使一位长者吃惊。
