1. Corollary
Units & Measurements · Math Abbreviations
A result that follows quickly from a theorem just proved, abbreviated Cor in lecture notes and references such as "Cor 2.5". Corollaries usually need only a short argument.
Example: Cor 5.3: Every finite integral domain is a field.
The word comes from Latin corollarium, originally a garland or small gift given as a bonus. Textbooks usually number corollaries in the same sequence as theorems and lemmas, so a reference such as Cor 2.5 points to a specific section.
2. Corner
Geography & Places · Address Abbreviations

Example: Our farm stand is at 8 Pike Cor, open weekends.
