Synonym Chooser

How is the word sound different from other adjectives like it?

Some common synonyms of sound are cogent, convincing, telling, and valid. While all these words mean "having such force as to compel serious attention and usually acceptance," sound implies a basis of flawless reasoning or of solid grounds.

When might cogent be a better fit than sound?

While in some cases nearly identical to sound, cogent may stress either weight of sound argument and evidence or lucidity of presentation.

the prosecutor's cogent summation won over the jury

When is convincing a more appropriate choice than sound?

The meanings of convincing and sound largely overlap; however, convincing suggests a power to overcome doubt, opposition, or reluctance to accept.

While the synonyms telling and sound are close in meaning, telling stresses an immediate and crucial effect striking at the heart of a matter.

a telling example of bureaucratic waste

When can valid be used instead of sound?

In some situations, the words valid and sound are roughly equivalent. However, valid implies being supported by objective truth or generally accepted authority.

a valid reason for being absent
