Legal Definitions - R.

Definition: R is an abbreviation that can have several meanings:

1. REX: This is a Latin word that means "king" or "ruler." In some contexts, R can be used as an abbreviation for Rex, especially in genealogy or historical research.
2. REGINA: This is another Latin word that means "queen." In some contexts, R can be used as an abbreviation for Regina, especially in genealogy or historical research.
3. RANGE: In mathematics, R can be used to represent the set of real numbers, which includes all rational and irrational numbers.
4. Trademarks: When contained in a circle (and often superscripted), the symbol R indicates that a trademark or servicemark is registered in the U.S. Patent and Trademark Office. For example, the Nike logo is often accompanied by the symbol "R" to indicate that it is a registered trademark.

For example, if you were researching your family history and found a document that referred to "Henry R," it might mean that Henry was a king or ruler (i.e. Henry Rex). Alternatively, if you were studying math and saw an equation that included "x ∈ R," it would mean that x is a real number. Finally, if you were looking at a product with a logo that included the symbol "R," it would mean that the logo is a registered trademark.
