The word PAVE is a U.S. Air Force program identifier relating to electronic systems. Prior to 1979, PAVE was said to be a code word for the Air Force unit responsible for the project. PAVE was used as an inconsequential prefix identifier for a wide range of different programs, though backronyms and alternative meanings have been used. For example, in the helicopters PAVE Low and PAVE Hawk it was said to mean Precision Avionics Vectoring Equipment, but in PAVE PAWS it was said to mean Precision Acquisition Vehicle Entry.

Pave may refer to:

• Pavement (disambiguation)
• Stonesetting method
• Pavé (road surface)
• Pave Maijanen, a Finnish musician
• Zaspal Pave, Croatian folk song

A sett, usually referred to in the plural and known in some places as a Belgian block, is a broadly rectangular quarried stone used for paving roads. Formerly in widespread use, particularly on steeper streets because setts provided horses' hooves with better grip than a smooth surface, they are now encountered rather as decorative stone paving in landscape architecture. Setts are often inaccurately referred to as "cobbles": a sett is distinct from a cobblestone in that it is quarried or worked to a regular shape, whereas the latter is generally a small, naturally-rounded rock.
