Hyphenation RulesSet 7
Frequently Asked Questions
How do you correctly use hyphens in compound adjectives?
Hyphens are used in compound adjectives to connect two or more words that function as a single adjective before a noun. For example, "well-known author" uses a hyphen to combine "well" and "known" as a single descriptive unit. This rule ensures clarity and prevents ambiguity.
What is the correct hyphenation for compound numbers?
Compound numbers from twenty-one to ninety-nine are typically written with a hyphen, such as "thirty-five." This rule applies to ensure consistency and clarity in number writing conventions.
When should hyphens be used in compound modifiers before a noun?
Hyphens are used in compound modifiers before a noun to clarify that the words work together as a single modifier. For example, "high-quality paper" uses a hyphen to indicate that "high" and "quality" jointly modify "paper."
What is the difference between hyphens and dashes in punctuation?
Hyphens are shorter and used to join words or parts of words, such as in compound adjectives. Dashes, which are longer, are used to indicate a break in thought or to set off a clause for emphasis. For example, "The meeting—delayed by an hour—finally began."
How do you apply hyphenation rules to ages used as adjectives?
When ages are used as adjectives before a noun, they are typically hyphenated. For example, "a five-year-old child" uses a hyphen to connect "five," "year," and "old" as a single descriptive unit. This rule applies to ensure clarity and consistency.
