Chapter Inveigher to Investiture of I by Webster's Dictionary (1913 Edition)

Inverisimilitude
(In*ver`i*si*mil"i*tude) n. Want of verisimilitude or likelihood; improbability.

Inverse
(In*verse") a. [L. inversus, p. p. of invertere: cf. F. inverse. See Invert.]

1. Opposite in order, relation, or effect; reversed; inverted; reciprocal; — opposed to direct.

2. (Bot.) Inverted; having a position or mode of attachment the reverse of that which is usual.

3. (Math.) Opposite in nature and effect; — said with reference to any two operations, which, when both are performed in succession upon any quantity, reproduce that quantity; as, multiplication is the inverse operation to division. The symbol of an inverse operation is the symbol of the direct operation with -1 as an index. Thus sin-1 x means the arc whose sine is x.

Inverse figures (Geom.), two figures, such that each point of either figure is inverse to a corresponding point in the order figure. — Inverse points (Geom.), two points lying on a line drawn from the center of a fixed circle or sphere, and so related that the product of their distances from the center of the circle or sphere is equal to the square of the radius. — Inverse, or Reciprocal, ratio (Math.), the ratio of the reciprocals of two quantities. — Inverse, or Reciprocal, proportion, an equality between a direct ratio and a reciprocal ratio; thus, 4 : 2 : : &frac13 : &frac16, or 4 : 2 : : 3 : 6, inversely.

Thus the course of human study is the inverse of the course of things in nature.

Inversion
(In*ver"sion) n. [L. inversio: cf. F. inversion. See Invert.]

1. The act of inverting, or turning over or backward, or the state of being inverted.

It is just the inversion of an act of Parliament; your lordship first signed it, and then it was passed among the Lords and Commons.

Dryden.

3. (Mil.) A movement in tactics by which the order of companies in line is inverted, the right being on the left, the left on the right, and so on.

4. (Math.) A change in the order of the terms of a proportion, so that the second takes the place of the first, and the fourth of the third.

5. (Geom.) A peculiar method of transformation, in which a figure is replaced by its inverse figure. Propositions that are true for the original figure thus furnish new propositions that are true in the inverse figure. See Inverse figures, under Inverse.

6. (Gram.) A change of the usual order of words or phrases; as, "of all vices, impurity is one of the most detestable," instead of, "impurity is one of the most detestable of all vices."

7. (Rhet.) A method of reasoning in which the orator shows that arguments advanced by his adversary in opposition to him are really favorable to his cause.

8. (Mus.) (a) Said of intervals, when the lower tone is placed an octave higher, so that fifths become fourths, thirds sixths, etc. (b) Said of a chord, when one of its notes, other than its root, is made the bass. (c) Said of a subject, or phrase, when the intervals of which it consists are repeated in the contrary
