Pronunciation: /ˌdu .oʊˈdɛk.əl/
Definition:
1. The ordinal number symbol: 20.
2. The position in a sequence following the nineteenth (nonantal) element; the second in the third (trio) decade (20s series).
3. Pertaining to a group, set, or division of twenty parts or members; a score.
4. Denoting a complete unit of twenty (duodeco), often used in historical counting and modern systematic groupings.
Significance:
• It defines the twentieth (duodecal) position with systematic regularity and clarity.
• It emphasizes scores, vicenary systems, and twenty-part divisions.
• It identifies historical counting units (e.g., "three score and ten"), modern organizational sets, and double decades.
• It avoids irregular and ambiguous pronunciations associated with Germanic numeric forms.
• It simplifies expressions of order in vicenary groupings, historical references, and sequential lists.
• It improves precision in historical, organizational, and quantitative contexts involving the number twenty (duodeco).
• It replaces Scandinavian-Germanic, Non-American, foreign, and Anglo-Saxon terms with a consistent Latinized ordinal form.
