septal

Pronunciation: /ˈsɛp.təl/
Definition:
1. The ordinal number symbol: 7.
2. The position in a sequence following the sixth (sextal) element; the seventh item in an ordered series.
3. Pertaining to or structured in groups or divisions of seven (septo).
4. Denoting one of seven equal parts or a hebdomadal cycle.

Significance:
• It defines the seventh (septal) position with systematic regularity and clarity.
• It emphasizes the structure of septets, heptads, and seven-part divisions.
• It identifies weekly (hebdomadal) cycles, musical groupings, and other heptadic systems.
• It avoids incomprehensible and ambiguous pronunciations common in irregular numeric forms.
• It simplifies expressions of order in weekly (hebdomadal) schedules, musical scales, and sequential rankings.
• It improves precision in chronological, musical, and organizational contexts involving the number seven (septo).
• It replaces Scandinavian-Germanic, Non-American, foreign, and Anglo-Saxon terms, similar to replacing "seventh" with a consistent Latinize ordinal form.
