CURIOUS is the opposite of:

Inquisitive is synonymous with curious, as it describes someone who is eager for knowledge and asks questions. Rather than representing an opposite, inquisitive reinforces the idea of being curious, as both terms convey a sense of active interest in understanding the world.

Interested suggests a level of attention or concern about a subject, which is closely related to curiosity. While one can be interested in something, it does not convey the full depth of engagement that curiosity embodies. Therefore, interested is more aligned with curiosity rather than its opposite.

Questioning involves seeking answers or clarification and is often a product of curiosity itself. While questioning can arise from a curious mind, it does not represent an opposite; rather, it is a method through which curiosity manifests.

Prying implies an intrusive interest in someone else's affairs, which can stem from curiosity but carries negative connotations. Although it may appear related, it does not serve as the opposite of curious, as prying is often perceived as overstepping boundaries rather than a neutral state of indifference.
