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

*.*
