The Art of Hyphenation: A Guide to Correctly Punctuating Compound Adjectives

Understanding Compound Adjectives

Compound adjectives are words that are made up of two or more words that work together to describe a noun. They can be written as separate words, a hyphenated word, or a single word. In the case of the phrase "A well known scientist," we need to determine the correct way to hyphenate it.

The Rules of Hyphenation

The rules of hyphenation can be complex, but there are some general guidelines to follow. According to the Chicago Manual of Style, a compound adjective that comes before the noun it modifies should be hyphenated. This is known as a "pre-noun" compound adjective.

Option A: A well-known-scientist named Dr. Mary Enig

In this option, the phrase "well-known-scientist" is hyphenated. This is a correct way to hyphenate the phrase, as it is a pre-noun compound adjective. The hyphen is used to indicate that the two words are working together to describe the noun "scientist."

Option B: A well-known scientist named Dr. Mary Enig

In this option, the phrase "well-known" is hyphenated, but the word "scientist" is not. This is also a correct way to hyphenate the phrase, as the hyphen is used to indicate that the two words are working together to describe the noun "scientist."

Option C: A well known scientist-named Dr. Mary Enig

In this option, the phrase "well known" is not hyphenated, but the word "scientist-named" is. This is not a correct way to hyphenate the phrase, as the hyphen is used to indicate that the two words are working together to describe the noun "scientist," but it is not necessary to hyphenate the word "scientist" in this case.

Option D: NO CHANGE

In this option, the phrase is not hyphenated at all. This is not a correct way to hyphenate the phrase, as the hyphen is necessary to indicate that the two words are working together to describe the noun "scientist."

Conclusion

In conclusion, the correct way to hyphenate the phrase "A well known scientist" is either Option A: A well-known-scientist named Dr. Mary Enig or Option B: A well-known scientist named Dr. Mary Enig. Both of these options are correct, as they use the hyphen to indicate that the two words are working together to describe the noun "scientist."
