How to use Hyphen with Compound modifiers?

When two or more words collectively modify a noun and precede it, a hyphen makes their combined meaning clear. For example, “a high-risk investment” shows that the investment is “high risk”, not that the investment and risk are high separately.

Before the Noun

When a compound modifier comes before the noun it modifies, use a hyphen to link the words together. This indicates that the words function as a single idea or unit.

• Example: “A well-known actor”. Here, “well-known” describes “actor.”

After the Noun

If the compound modifier comes after the noun and there is no ambiguity, it’s usually not necessary to use a hyphen.

• Example: “The actor is well known”.

With Numbers

When compound modifiers involve numbers, hyphenate them before the noun they modify.

• Example: “A 20-year-old wine”. Here, “20-year-old” modifies “wine.”

Adverb-Adjective Combinations

Do not hyphenate compound modifiers when the first word is an adverb ending in “-ly”.

• Example: “A poorly written script”. No hyphen is needed because “poorly” is an adverb modifying “written.”

Avoiding Ambiguity

Hyphens in compound modifiers can prevent misunderstanding by making relationships between words clearer. For example:

• Without hyphen: “She saw a man eating shark”.
• With hyphen: “She saw a man-eating shark”. Clarifies that the shark eats men, not, she saw a man who was eating shark meat.

Hyphens in compound modifiers involving fractions

When a fraction describes a noun and functions as an adjective, you should hyphenate the entire modifier, including the fraction and the noun it modifies. For example:

• A two-thirds majority
• A three-quarter mile race
• Half-inch nails
• A five-eighths inch drill bit

In English grammar, a hyphen (-) is a punctuation mark used to join words or parts of words. It serves several purposes, including creating compound words, avoiding ambiguity, and breaking words at the end of lines.

The hyphen, a small punctuation mark (-), plays a crucial role in enhancing clarity, precision, and readability in written English. It’s primarily used for forming compound words like “mother-in-law” and “part-time,” where it clarifies meaning and indicates a close relationship between words.
