恐れがある

恐れがある expresses that there is a risk, danger, or possibility of something undesired happening. It is used to indicate concern about a potential negative outcome. The subject of the sentence is the thing that is feared or that carries risk, marked with が, and ある signals the existence of that condition. This pattern is common in formal or written contexts, including news reports, analyses, and warnings, but it can also appear in conversation when you want to calmly acknowledge a potential downside. It is not used for concrete fears of people’s feelings (that would use 心配する) or for strong emphatic certainty. Structure tends to be more about objective possibility rather than personal worry. Examples: ・台風の接近で被害が出る恐れがある。 (There is a fear that damage will occur due to the approaching typhoon.) ・この薬には副作用の恐れがある。 (There is a possibility of side effects with this medicine.) ・雨が強くなれば交通機関の乱れの恐れがある。 (If the rain gets heavier, there is a risk of disruption to transportation.)
