Do you have to have a proper noun in every sentence?

Answer 1

Not unless it is used as a proper noun. A proper noun is the name or title of a specific person, place, or thing. A proper noun is always capitalized.

The noun 'sentence' is a common noun, a general word for a grammatical unit; a general word for punishment set by a court. A common noun is capitalized only when it's the first word in a sentence.

Examples:

Is this sentence correct? (common noun, lower case c)

He received a sentence of ten years. (common noun, lower case c)

Examples for proper nouns:

Henry County Sentence Enforcement Department, McDonough GA

Sentence Gardens (street) in Templeton, Wales

Answer 2

No, the word "I" is a pronoun.
A noun is a word for a person, a place, or a thing.

A proper noun is the name of a specific person, place, or thing.

A pronoun is a word that takes the place of a noun in a sentence.
The pronoun "I" is a personal pronoun.

• A personal pronoun is a word that takes the place of a noun for a specific person or thing.
  
• The personal pronoun "I" takes the place of a singular noun (name) for the person speaking as the subject of a sentence or a clause.
  
• The corresponding first person, singular pronoun that functions as the object of a verb or a preposition is "me".
  

Example:
When I saw the posting for this job, I knew it was right for me.

Answer 3

No, many sentences do not have proper nouns, including this one. Your question sentence is also without proper nouns.
