How it's used

This expression describes a lack of focus or consistency in character, often implying a restless or flighty nature. It is most frequently applied to children or teenagers, but can also describe adults who struggle to commit to a single path or task. It carries a slightly critical tone, suggesting that the person needs to settle down and become more disciplined.

Common phrases

having a flighty personality

Common mistake

Do not confuse this with simply being active or energetic, which is usually described as 好動. 冇定性 specifically highlights the inability to stay focused or maintain a consistent effort, rather than just having a high energy level.
