* Adjectives: Yes, "loud" and "soft" are definitely adjectives. They describe qualities of nouns: "a loud noise," "a soft pillow."
* Proper Adjectives: Proper adjectives are derived from proper nouns (names of specific people, places, or things). They are always capitalized. Examples include: "American" (from America), "Shakespearean" (from Shakespeare), "French" (from France).
"Loud" and "soft" are not derived from proper nouns, so they are not proper adjectives. They are simply descriptive adjectives.
However, there are some instances where "loud" and "soft" might be used as part of a proper noun:
* A band name: "The Loud Ones" or "The Soft Sounds"
* A product name: "Loud & Clear" detergent
* A nickname: "Loudmouth" or "Softie"
In these cases, "loud" and "soft" are part of a proper noun and should be capitalized.
In summary:
* "Loud" and "soft" are regular adjectives, not proper adjectives.
* They can be part of a proper noun, and then they would be capitalized.
