How Do I Work With Common And Proper Nouns?

Common nouns name persons, places, things and ideas.
Examples: man, friend, librarian, aunt, giraffe, ant, school, city, table, computer, beauty, religion, sadness.

When writing titles of songs and albums which do you capitalize or underline?

When writing titles of songs and albums, it is common to capitalize the main words in the title. This includes nouns, pronouns, verbs, adjectives, and adverbs. Words such as articles (e.g., "the," "a"), conjunctions (e.g., "and," "or"), and prepositions (e.g., "on," "over") are typically not capitalized unless they are the first or last word of the title.

For example:
- "Bohemian Rhapsody" (capitalizing the nouns)
- "Back in Black" (capitalizing the preposition "in" because it is the first word of the title)

As for underlining, it is not a common practice in modern writing. Instead, titles of songs and albums are typically enclosed in quotation marks.

For example:
- "Don't Stop Believin'" (enclosing the title in quotation marks)

Remember to always follow any specific style guidelines or requirements provided by the publication or organization you are writing for, as they may have their own rules for capitalization and formatting of titles.
