Pluralvoids
- 1A space with nothing in it; a vacuum.
The probe's signal faded as it sailed out into the void.
No new leader emerged to fill the void left by the founder's death.
UsageOften fill the void or leave a void in someone's life.
Note
Fill the void is the phrase that carries this noun into everyday English: in An Essay on Criticism (1711) Pope has pride step in to fill up all the mighty void of sense, and a death or a departure still leaves a void that someone must fill. Used alone, the void is space itself, or the dark beyond the known.

Note
Astronomers picture the universe as a web: galaxies crowd into walls and filaments, and the voids are the vast cells between them, holding far less matter than average. They are among the largest structures ever mapped, and their sizes and shapes help test models of how cosmic structure grew.

Engineers left a narrow void between the old brick wall and the new steel frame.
Similarcavity, space, gap, hollow
Note
Many voids are designed in: a raised floor or suspended ceiling leaves one to carry ducts, pipes and cables, and a double-skin facade leaves one for air to move through. Because a void can also carry fire and smoke out of sight, building codes call for barriers that break long voids into sections.

Note
Scripture gave this sense its lasting phrases: God's word shall not return void, and the counsel of Judah is made void, both in the 1611 Bible. Make void slides easily toward the legal sense of having no force; for plain futility, modern writers reach for useless or pointless.

In C, a void function simply ends with return or reaches its closing brace.
Note
In C and the languages that borrow its syntax, such as Java and C#, void is the keyword written where a return type would go: void draw(). C also uses it for an empty parameter list, int main(void), and for a pointer to data of unspecified type, void *, so not every void in C code means the same thing.

- 15A pocket of vapor inside a moving fluid, formed by cavitation.
Engineers raised the inlet pressure so that no void could form at the pump's intake.
High-speed cameras caught a void growing and collapsing on the propeller blade in a fraction of a second.
Note
A cavitation void forms where a liquid's local pressure falls below its vapor pressure, and it collapses violently once the flow carries it back into higher pressure. Those repeated collapses pit pump impellers and ship propellers, so designers shape blades and set inlet pressures to limit voids and the damage they do.

A single missing atom is a vacancy; when vacancies drift together and merge, they form a void, a tiny three-dimensional hole in the lattice. Under neutron bombardment metals can grow so many voids that they swell, which is why engineers must allow for void swelling in reactor parts.

Her splinter bid told partner that she held a singleton or a void in spades.
Note
A void is the far end of shortness, beyond the doubleton and the singleton. Because it lets a player ruff the first time the suit is led in a trump contract, it weighs heavily when a hand is valued, and many partnerships have special bids, such as splinters, to show one.
