Usage notes

• Ability, capacity : these words come into comparison when applied to the higher intellectual powers.
  • Ability has reference to the active exercise of our faculties. It implies not only native vigor of mind, but that ease and promptitude of execution which arise from mental training. Thus, we speak of the ability with which a book is written, an argument maintained, a negotiation carried on, etc. It always supposes something to be done, and the power of doing it.
  • Capacity has reference to the receptive powers. In its higher exercises it supposes great quickness of apprehension and breadth of intellect, with an uncommon aptitude for acquiring and retaining knowledge. Hence it carries with it the idea of resources and undeveloped power. Thus we speak of the extraordinary capacity of such men as Lord Bacon, Blaise Pascal, and Edmund Burke. "Capacity," says H. Taylor, "is requisite to devise, and ability to execute, a great enterprise."
• The word abilities, in the plural, embraces both these qualities, and denotes high mental endowments.

   • 1830, Solomon Pearson Miles, Thomas Sherwin, Mathematical Tables: Comprising Logarithms of Numbers, […] , page 69,

     It is evident, moreover, that as the logarithms of numbers, which are tenfold, the one of the other, do not differ except in their characteristics, it is sufficient that the tables contain the fractional parts only of the logarithms.

   • 1911, F. T. Swanwick, Elementary Trigonometry, Cambridge University Press, page 60,

     As the sine and cosine are always proper fractions their logarithms are negative, i.e. have negative characteristics. When we are given an angle, it is impossible to say, from inspection of the angle, what the characteristic of the logarithm of its sine, cosine or tangent may be; so the characteristics have to be printed with the mantissae.

   • 1961, Principles and Applications of Mathematics for Communications-Electronics, [U.S.] Department of the Army, page 69,

     Similarly, the characteristic for .003 is ?3, and the characteristic for .0003 is ?4.

4. (algebra, field theory, ring theory) For a given field or ring, a natural number that is either the smallest positive number n such that n instances of the multiplicative identity (1) summed together yield the additive identity (0) or, if no such number exists, the number 0.

     Let R be a Noetherian factorial ring of characteristic p which is not a field.

   • 1993, S. Warner, Topological Rings, Elsevier (North-Holland), page 424,

     Traditionally, a complete, discretely valued field of characteristic zero, the maximal ideal of whose valuation ring is generated by the prime number p, has been called a p-adic field. In our terminology, the valuation ring of a p-adic field is a Cohen ring of characteristic zero whose residue field has characteristic p, and consequently a p-adic field is simply the quotient field of such a Cohen ring.
