Emily Thomas

Imagine a world without hyphens, where words like “well-being” become “wellbeing” and “mother-in-law” becomes “motherinlaw.” It’s hard to fathom, right? Hyphens may be small, but they play a crucial role in our language. They bring words together, connecting ideas and clarifying meanings. From compound words to prefixes and suffixes, hyphens ensure that our sentences flow smoothly and our thoughts are expressed clearly. So, let’s take a closer look at the most common use of a hyphen and explore its importance in our everyday communication.

Words with Compound Meaning

Noun-Noun Compounds

Noun-noun compound words are formed by combining two nouns together to create a new word that represents a specific concept or idea. These compounds often act as a single unit and can modify other nouns or serve as subject or object of a sentence. Examples of noun-noun compounds include “sunflower,” “coffee table,” and “raincoat.” When using these compound words, it is important to ensure that the hyphen is correctly placed to maintain clarity and avoid confusion.

Verb-Noun Compounds

Verb-noun compound words are formed by combining a verb and a noun together to create a new word that describes an action or process. These compounds often represent activities or tasks and can act as both verbs and nouns within a sentence. Examples of verb-noun compounds include “firefighter,” “bookshelf,” and “shopping cart.” When utilizing these compound words, it is crucial to place the hyphen appropriately to maintain the intended meaning.

Adjective-Noun Compounds

Adjective-noun compound words are formed by combining an adjective and a noun together to create a new word that portrays a specific quality or characteristic. These compounds modify the noun they are associated with and can be used to describe various objects, people, or situations. Examples of adjective-noun compounds include “blueberry,” “hardworking,” and “elephant-sized.” Ensuring the correct placement of the hyphen is essential to preserve the intended meaning of these compound words.

Adverb-Adjective Compounds

Adverb-adjective compound words are formed by combining an adverb and an adjective together to create a new word that expresses the manner or quality of an action. These compounds are often used to provide precise descriptions and enhance the overall meaning of a sentence. Examples of adverb-adjective compounds include “well-known,” “easily accessible,” and “highly skilled.” Paying attention to the hyphen placement in these compound words is crucial to convey the intended message accurately.

Adverb-Verb Compounds

Adverb-verb compound words are formed by combining an adverb and a verb together to create a new word that describes the manner or way in which an action is carried out. These compounds help provide additional information on how an action is performed and are commonly used in various fields. Examples of adverb-verb compounds include “carefully analyze,” “quickly respond,” and “efficiently manage.” Placing the hyphen in the correct position is important to avoid any misinterpretation of these compound words.

Word Breaks at End of a Line

Syllable Division

Syllable division plays a vital role in determining where to break a word at the end of a line to maintain proper spacing and readability. Splitting words correctly can help ensure that readers can easily recognize and comprehend the word being conveyed. It is advisable to break words at syllable boundaries by separating the syllables with a hyphen if necessary.

Avoiding Awkward Spacing

When breaking a word at the end of a line, it is crucial to avoid creating awkward spacing that may confuse or hinder understanding. If breaking a word would result in a single letter at the end of a line, it is preferable to move the entire word to the next line. This helps maintain a visually pleasing layout and prevents any confusion for the reader.

Joining Words

Compound Adjectives

Compound adjectives are two or more adjectives that are used together to describe a noun. When using compound adjectives, it is important to hyphenate them to indicate that they work together to modify the noun. For example, “high-quality,” “well-known,” and “five-year-old” are all examples of compound adjectives. Hyphenating compound adjectives improves clarity and helps readers understand the intended meaning of the sentence.

Prefixes and Suffixes

When joining words with prefixes or suffixes, it is essential to consider whether hyphenation is required. While some combinations may not require a hyphen, others do to prevent confusion. For instance, “uncooperative” does not require a hyphen, but “re-examine” and “self-confident” do. Hyphenating words with prefixes and suffixes helps readers understand the individual components and their relationship within the word.

Multiple Adjectives

When using multiple adjectives to describe a noun, a hyphen is only required if the adjectives together form a compound adjective. If the adjectives are simply listed before a noun, no hyphen is necessary. For example, “a red sports car” does not require a hyphen but “a well-known author” does. Using hyphens correctly in multiple adjective constructions ensures that the intended meaning is clear to the reader.

Coordinating Prefixes

Coordinating prefixes, such as “co-” and “non-,” often require a hyphen when used in combination with nouns or adjectives. Examples include “co-worker,” “non-essential,” and “anti-inflammatory.” Proper hyphenation with coordinating prefixes helps maintain clarity and eliminates any ambiguity that may arise.

Ranges and Connections

Number Ranges

When expressing number ranges, it is common to use a hyphen to connect the two numbers. For example, “10-20,” “50-100,” and “1,000-2,000” are all examples of number ranges. Hyphenating number ranges assists readers in understanding that a range is being conveyed rather than a single value.

Time Ranges

Similar to number ranges, time ranges are typically expressed with a hyphen. For instance, “9:00-10:00,” “Monday-Friday,” and “June-August” are all examples of time ranges. Hyphenating time ranges clarifies that a span of time is being referenced, ensuring the reader recognizes the intended meaning.

Page Ranges

Page ranges are often indicated using a hyphen to connect the first and last pages. For example, “pages 10-15,” “pages 50-75,” and “pages 100-125” all represent page ranges. Hyphenating page ranges allows readers to understand that a continuous sequence of pages is being referred to.

Connecting Prefixes

Connecting prefixes, such as “re-,” “pre-,” and “post-,” are commonly hyphenated when used in combination with words or phrases. Examples include “re-evaluate,” “pre-existing,” and “post-operative.” Proper hyphenation with connecting prefixes ensures clarity and eliminates any confusion that may arise.

Spelling and Pronunciation

Spelling Out Words

In certain situations, it may be necessary to spell out words using hyphens to ensure clarity and to avoid ambiguity. Words such as “a-n-n-u-a-l,” “j-a-c-k-e-t,” and “e-l-e-p-h-a-n-t” are examples of spelling out words using hyphens. Hyphenation aids in understanding the individual letters or syllables within a word, especially in contexts where precise spelling is crucial.

Avoiding Ambiguity

Hyphenation can also help avoid ambiguity in certain situations, especially when two words together may be misinterpreted if not hyphenated. For example, “re-cover” versus “recover,” or “re-form” versus “reform.” In these cases, the hyphen clarifies the intended meaning, reducing the risk of misunderstanding.

Pronouncing Words

Hyphenation can provide guidance on the pronunciation of certain words, particularly when it comes to separating syllables. Placing a hyphen between syllables helps readers accurately pronounce the word. Examples include “po-ta-to,” “cam-e-ra,” and “im-poss-i-ble.” The hyphen serves as a visual cue to indicate how the word should be pronounced.

Accent Marks

In some cases, accent marks are indicated with hyphens to assist in ensuring correct pronunciation. Words such as “café,” “résumé,” and “naïve” utilize hyphens to indicate the presence of an accent mark. Hyphenation helps distinguish the pronunciation of these words from words with similar spellings but different meanings.

Dividing Numbers and Fractions

Numbers and Units

In specific contexts, hyphens are used to separate numbers from their units of measurement. Examples include “10-meter,” “5-pound,” and “3-inch.” Hyphenating numbers and units clarifies that they should be considered as a single entity and avoids confusion or misinterpretation.


When expressing fractions, hyphens are used to connect the numerator and denominator. Examples include “1/2,” “3/4,” and “5/8.” Hyphenating fractions ensures that they are interpreted correctly as a single value, rather than separate numbers.

Measurement Notation

In certain measurement notations, hyphens are used to indicate a range of values. For example, “30-40 mg,” “10-15 cm,” and “5-10 kg” represent measurement ranges. Using hyphens in measurement notation helps the reader understand the span of values being referred to.

Word Formation and Derivation


Hyphens are commonly used with prefixes to clarify word formation and aid in reader comprehension. Examples include “ex-husband,” “pre-existing,” and “anti-inflammatory.” Hyphenating words with prefixes assists in differentiating the meaning of the word from similar words without the prefix.


Similar to prefixes, hyphens are often used with suffixes to indicate word formation. Examples include “child-friendly,” “runner-up,” and “high-pitched.” Hyphenating words with suffixes helps convey the intended meaning and avoids any potential confusion.

Particle Words

Particle words, such as “self-,” “all-,” and “cross-,” are frequently connected with hyphens to indicate their relationship with other words. Examples include “self-esteem,” “all-inclusive,” and “cross-reference.” Proper hyphenation with particle words aids in understanding the overall meaning of the word and the relationship between its components.

Compounds and Phrases

Hyphenation is crucial when combining two or more words to form a compound or a phrase. Examples of this include “mother-in-law,” “jack-of-all-trades,” and “breakfast-to-go.” Hyphenating compound words and phrases helps readers recognize that these words work together to convey a specific concept or idea.

Showing Omissions


When indicating omissions in abbreviations, a hyphen is commonly used. Examples include “I-20” for “Interstate 20,” “C-Section” for “cesarean section,” and “T-shirt” for “tee shirt.” Hyphenating abbreviations assists in understanding the omitted letters or words and ensures the accurate interpretation of the abbreviation.


Contractions, where words are combined and letters are omitted, are often indicated with a hyphen. Examples include “can’t” for “cannot,” “I’m” for “I am,” and “don’t” for “do not.” Hyphens in contractions help readers recognize the omission of letters and understand the intended meaning.

Missing Words

In certain contexts, the use of hyphens can indicate missing words. For example, “fill-in-the-blank” indicates that a word or words need to be inserted, and “on-the-go” implies activities or tasks done while moving. Hyphenation allows readers to understand that something is missing and prompts them to engage with the context to fill in the blanks.

Hyphenating Proper Nouns

Names with Multiple Parts

Hyphenation is often necessary in proper nouns that consist of multiple parts, such as given names, surnames, or place names. Examples include “Mary-Kate Olsen,” “Martin Luther King Jr.,” and “New York-based.” Hyphenating proper nouns with multiple parts helps indicate the relationship between the components and ensures accurate recognition and understanding.

Foreign-Based Names

Proper nouns with foreign-based names may require hyphenation to maintain accuracy and clarity. Examples include “Jean-Paul Gaultier,” “Eva María Perón,” and “Muhammad Ali Jinnah.” Hyphenating foreign-based names assists in distinguishing individual components and pronunciations, preventing misinterpretation.

Distinguishing Similar Words

Adverb or Preposition

Hyphenation can help distinguish between an adverb and a preposition when the same word is used in both contexts. For example, hyphenation is used in “well-known” (adjective) versus “well-qualified” (adverb + adjective). Proper hyphenation differentiates the function of the word in the sentence and clarifies its intended meaning.

Noun or Verb

In certain cases, hyphens aid in distinguishing between a noun and a verb when the same word is used in both contexts. For instance, “record” can be a noun meaning a document or a verb meaning to document, while “re-cord” is a hyphenated form of the verb. Hyphenating words in such cases avoids ambiguity and ensures accurate interpretation.

Contraction or Possessive

Hyphenation is essential when differentiating between a contraction and a possessive form of a word. For example, “you’re” (contraction of “you are”) versus “your” (possessive form). Proper hyphenation helps convey the intended meaning of the word and eliminates confusion between these similar constructs.

In conclusion, hyphenation plays a significant role in various aspects of language, such as word formation, ranges, pronunciation, and distinguishing similar words. Understanding the correct usage of hyphens enhances clarity, readability, and overall communication when utilizing compound words, indicating omissions, joining words, dividing numbers, spelling, and forming derivatives. By adhering to the guidelines outlined in this article, you can master the art of hyphenation and effectively convey your message.
