What does 'tenuous' mean?

The word 'tenuous' is used to describe something that is weak, fragile, or lacking in substance. It often refers to arguments, connections, or relationships that are not well-founded or are insubstantial. In this context, the definition aligns perfectly with the idea of having little substance or significance.

For example, if someone presents a tenuous argument, it suggests that their reasoning is weak and doesn't hold much weight or validity. This term conveys a sense of delicacy or uncertainty, indicating that the thing being described is not robust or well-supported. Thus, the choice that defines 'tenuous' as having little substance or significance is the correct interpretation of the term.
