sound argument
Valid persuasive case
A sound argument is one that is both logically valid and has true premises—meaning its conclusion must be true.
The term comes from formal logic but appears in everyday debate: That's not a sound argument; your premise is flawed.
Distinguished from merely valid arguments, which follow correct logical form but may rest on false assumptions.
