( ) can be left out · other words may come before, between and after
How it works
Means a feared or unwanted event nearly occurred but did not. For undesired outcomes, 差点儿 and 差点儿没 mean the same thing (both: it almost happened but didn't). For a hoped-for outcome, 差点儿 means it nearly failed to happen, while 差点儿没 means it barely did happen.
Examples
我差点儿迟到了。
Wǒ chàdiǎnr chídào le.
I almost arrived late.
他差点儿没赶上火车。
Tā chàdiǎnr méi gǎnshàng huǒchē.
He barely caught the train.
