~かねない: meaning, usage and examples
~かねない means: might... / could possibly... (negative).
How to form it
<Verb ます-stem> + かねない
Examples
このまま放置すると、大事故になりかねない。
If left as is, it could possibly lead to a major accident.
毎日こんなに残業していたら、倒れかねない。
If I keep working this much overtime every day, I could end up collapsing.
睡眠不足のまま運転すると、事故を起こしかねない。
Driving without enough sleep could lead to an accident.
その言い方では、相手に誤解されかねませんよ。
If you put it that way, the other person could misunderstand you.
When to use it
Use かねない to say that a bad result could easily happen if a situation continues or if someone acts in a certain way. It often warns about a cause and its possible effect, as in 睡眠不足で運転すると、事故を起こしかねない (driving without enough sleep could lead to an accident).
Nuance
Slightly formal; used in both speech and writing. Only for negative outcomes. It often contains a note of criticism or worry about someone's behavior. The positive form かねる means "cannot do" (お答えしかねます), which is a different pattern.
Compare
おそれがある is a neutral, objective warning used in news (台風のおそれがある). かねない adds criticism of a cause: そんな運転では事故を起こしかねない. かもしれない is a neutral guess that can describe good or bad outcomes alike: 合格するかもしれない.
Tip: Shape is negative, meaning is positive: かねない = "could well happen". Do not read it as "will not happen".
