When aiming to convey that an argument is compelling, opt for clearer alternatives like "present a solid argument" or "build a convincing case".
Common error
A common mistake is pairing the noun "case" with the incorrect preposition. Remember, one does not typically act "on" a case but rather "makes" or "presents" it. Using "on" can obscure the intended meaning and weaken the overall statement.
