In order to speak with precision about stance-duration (1 + 3) I’ve had to invent many new terms. I’ve tried to make them parallel to the corresponding length-time (3 + 1) terms and to follow scientific practice of using Greek and Latin roots. These new terms are placed parallel to their corresponding terms in two pdf’s, ** Parallel Glossary for Classical Physics** and

*.*

**Parallel Glossary for Relativity Physics**The term *space* is the space of motion, not merely the space of length or duration. So there is space measured by length – length space – as well as space measured by duration – duration space. Note that the term *time* has multiple meanings: duration, distime, dischronment, duration space, 3D time, and scalar time.

The terms below are presented in this format: term in bold, definition, units, etymology, and in some cases a suggested symbol. Other terms in this glossary are in italics.
