Is the abbreviation Pkwy. a proper noun? How about Mt.? It seems like mount would be a common noun since it is not with a proper noun, but it is capitalized.

Both Pkwy. and Mt. are part of proper nouns. Examples: Greenleaf Parkway, Mt. Denali.

* Greenleaf Pkwy

To determine if "Pkwy." and "Mt." are proper nouns or not, we need to understand their usage and grammatical rules.

Abbreviations can represent proper nouns, common nouns, or other types of words. In the case of "Pkwy." (an abbreviation for Parkway) and "Mt." (an abbreviation for Mount), here's how we can determine their noun classification:

1. Context: First, we should consider the context in which these abbreviations are used. If they are used as part of a specific location or name, it suggests that they are proper nouns. For example, if someone is talking about "Smith Parkway" or "Mount Everest," then "Pkwy." and "Mt." would likely be considered proper nouns.

2. Capitalization: Another important clue is the capitalization of the abbreviation. In English grammar, proper nouns are capitalized while common nouns are not. This means that if "Pkwy." and "Mt." are capitalized in a sentence, there is a higher likelihood that they are being used as proper nouns.

Based on these principles, "Pkwy." and "Mt." are typically considered proper nouns. Although "mount" is a common noun, when it is abbreviated as "Mt." and capitalized, it functions as a specific name or location, making it a proper noun in that context.

It's worth noting that the classification of a noun can depend on the specific usage and context, so it's important to take these factors into consideration when determining if an abbreviation is a proper noun or not.
