The phrase “an angry” itself is incomplete for determining the type of noun it represents. However, if we consider a complete noun phrase like “an angry person,” the noun in question would be common.

Here’s why:

• Proper nouns refer to specific names of people, places, or organizations (e.g., John, Paris, Google). "An angry person" is not a specific name but a general description.
• Common nouns refer to general items, people, or concepts (e.g., person, book, city). "Person" in “an angry person” is a common noun.
• Collective nouns refer to a group of individuals or things considered as a single unit (e.g., team, flock). "An angry person" does not represent a group.
• Material nouns refer to substances or materials (e.g., gold, water). "Person" does not fit this category.

So, "an angry" (in the context of "an angry person") is a common noun.
