Use, usefulness, utility are comparable when they mean the character or the quality of serving or of being able to serve an end or purpose.
Use (see also USE 1 ) ( HABIT ) is the most general or least explicit of these terms; it usually implies little more than suitability for employment for some purpose stated or implied.
Usefulness , on the other hand, is employed chiefly with reference to definite concrete things that serve or are capable of serving a practical purpose.
Utility , which comes very close to usefulness , may be preferred in technical, economic, and philosophical speech or writing, where it is often regarded as a property that can be measured or altered (as in quantity or quality) or that can be viewed as an abstraction.
