   • 1683, Joseph Moxon, Mechanick Exercises: Or, the Doctrine of Handy-Works. Applied to the art of Printing., v 2, pp. 240–41:

     If it be only a Single Letter or two that drops, he thruſts the end of his Bodkin between every Letter of that Word, till he comes to a Space: and then perhaps by forcing thoſe Letters closer, he may have room to put in another Space or a Thin Space; which if he cannot do, and he finds the Space ſtand Looſe in the Form; he with the Point of his Bodkin picks the Space up and bows it a little; which bowing makes the Letters on each ſide of the Space keep their parallel diſtance; for by its Spring it thruſts the Letters that were cloſed with the end of the Bodkin to their adjunct Letters, that needed no cloſing.

   • 1979, Marshall Lee, Bookmaking, p 110:

     Horizontal spacing is further divided into multiples and fractions of the em. The multiples are called quads. The fractions are called spaces.

   • 2005, Phil Baines and Andrew Haslam, Type & Typography, 2nd ed, p 91:

     Other larger spaces – known as quads – were used to space out lines.

9. A set of points, each of which is uniquely specified by a set of coordinates; the number of coordinates specifying a point and the number of mutually perpendicular axes along which the coordinates lie are the same, and that is the number of dimensions of the space.
10. One's personal freedom to think or be oneself.
11. The state of mind one is in when daydreaming.
12. a generalized construct or set, the members of which have certain properties in common; often used in combination with the name of a particular mathematician
13. One of the five basic elements.
