Unlimited or generalized extent, physical or otherwise. • The distance between objects. • A physical extent across two or three dimensions (sometimes for or to do something). • A physical extent in all directions, seen as an attribute of the universe (now usually considered as a part of space-time), or a mathematical model of this. • The near-vacuum in which planets, stars and other celestial objects are situated; the universe beyond the earth's atmosphere. • The physical and psychological area one needs within which to live or operate; personal freedom. • Of time. • Free time; leisure, opportunity. • A specific (specified) period of time. • An undefined period of time (without qualifier, especially a short period); a while. • A bounded or specific extent, physical or otherwise. • A (chiefly empty) area or volume with set limits or boundaries; (architecture) such a space inside or outside a building, often with a specified use. • A position on the staff or stave bounded by lines. • A gap in text between words, lines etc., or a digital character used to create such a gap. • A piece of metal type used to separate words, cast lower than other type so as not to take ink, especially one that is narrower than one en (compare quad). • A gap; an empty place. • A set of points, each of which is uniquely specified by a number (the dimensionality) of coordinates. • A generalized construct or set whose members have some property in common; typically there will be a geometric metaphor allowing these members to be viewed as "points". Often used with a restricting modifier describing the members (e.g. vector space), or indicating the inventor of the construct (e.g. Hilbert space). • A field, area, or sphere of activity or endeavour. • Anything analogous to a physical space in which one can interact, such as an online chat room.
