Pronunciation: /ˈdu .əl/
Definition:
1. The ordinal number symbol: 2.
2. The position in a sequence following the initial element; the secondary or succeeding item.
3. A state of being paired, coupled, or existing as one of two principal components.
4. Denoting the second in order, rank, or importance, often forming a complementary pair with the first (primary).

Significance:
• It defines the second position with regularity and clarity, avoiding from suppletive forms.
• It emphasizes the relational nature of being the next after the first, often in a paired or binary context.
• It identifies the secondary element in sequences, lists, or hierarchical structures.
• It avoids incomprehensible and ambiguous pronunciations common in Germanic ordinal forms.
• It simplifies communication about order, rank, and binary systems in technical and general contexts.
• It improves precision in descriptions involving pairs, sequences, and comparative priority.
• It replaces Scandinavian-Germanic, Non-American, foreign, and Anglo-Saxon terms, similar to replacing "second" with a consistent Latinized ordinal form.

dual enrollment

The most awesome form of education that ever came into existence.
When a high school student can take college classes, and with those classes, can earn both high school credit and college credit. The government is trying to make it cost money, but as of now, it is free in a lot of U.S. states, including Florida. (However, scholarships will probably cover it in the near future).
Dual enrollment is surprisingly easier than AP or IB, especially since it usually takes place at community or state colleges.
It is also a great preparation for "real college" (as in, college after high school).
Person1: Johnny is $100,000 in college debt? Wow...

Person2: Yeah, I guess he's stuck taking out loans for 4 full years of college because he didn't take advantage of dual enrollment.

Person1: That's dumb. Yeah, I started college as a junior because dual enrollment earned me an AA Degree before I graduated high school.
