Earliest Uses of Some Words of Mathematics

James Joseph Sylvester, who introduced the words matrix, discriminant, invariant, totient, and Jacobian;
Gottfried Wilhelm Leibniz, who introduced the words variable, constant, function, abscissa, parameter, and coordinate;
René Descartes, who introduced the terms real number and imaginary number;
Sir William Rowan Hamilton, who introduced the terms vector, scalar, tensor, associative, and quaternion;
John Wallis, who introduced the terms induction, interpolation, continued fraction, mantissa, and hypergeometric series.

These pages attempt to show the first uses of various words used in mathematics. Research for these pages is ongoing, and a citation should not be assumed to be the earliest use unless it is indicated as such.

Mathematical Words: Origins and Sources by John Aldrich is an excellent article and companion to this web site.

James Joseph Sylvester, Nature 37 (1888), p. 152
Perhaps I may without immodesty lay claim to the appellation of Mathematical Adam, as I believe that I have given more names (passed into general circulation) of the creatures of mathematical reason than all the other mathematicians of the age combined.
