# Space-Time Glossary

In order to speak with precision about time terms (1 + 3) I’ve had to invent many new terms. I’ve tried to make them parallel to the corresponding space terms (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 terms below are from the Parallel Glossary of Space and Time for Classical Physics 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.
