The English language, with its rich history and vast vocabulary, often presents subtle distinctions that can trip up even seasoned writers. Among these common points of confusion are the words “comprize” and “comprise.” While they sound similar and are related in meaning, their correct usage is quite specific, and understanding these differences is crucial for clear and precise communication.
Understanding the Core Meanings
At its heart, the distinction between “comprize” and “comprise” lies in their grammatical function and the direction of the relationship they describe. “Comprise” is generally considered the more versatile and widely accepted term, often acting as a transitive verb that means “to consist of” or “to be made up of.” It denotes a whole that contains parts.
Think of “comprise” as indicating that something is composed of elements. For instance, a team might comprise several skilled players. The team is the whole, and the players are the parts it is made of.
Conversely, “comprize” is less common and its usage is often debated. When it is used, it typically functions as a transitive verb meaning “to include” or “to contain.” This flips the direction of the relationship, suggesting that something includes or contains other things.
For example, one might say “The collection comprized rare stamps.” Here, the collection is the whole, and it contains the stamps. However, many style guides recommend avoiding “comprize” in favor of “comprise” or other synonyms to prevent confusion.
The Dominance of “Comprise”
“Comprise” is the preferred term by most modern style guides, including The Associated Press Stylebook and The Chicago Manual of Style. Its usage is more straightforward and less prone to grammatical errors.
The phrase “comprise of” is a common error, stemming from a misunderstanding of “comprise’s” transitive nature. Since “comprise” already means “to consist of,” adding “of” is redundant and grammatically incorrect.
A correct sentence using “comprise” would be: “The United Kingdom comprises England, Scotland, Wales, and Northern Ireland.” This clearly states that the larger entity (the UK) is made up of the smaller entities (the constituent countries).
Another example illustrating the correct use of “comprise” is: “The novel comprises three distinct parts, each exploring a different theme.” Here, the novel is the whole, and its parts are the three sections.
When “Comprize” Might Be Seen
While “comprise” is the dominant and generally recommended word, “comprize” does appear in some older texts and is sometimes used by writers who intend it to mean “to include” or “to contain.” This usage, however, is often considered non-standard or archaic by contemporary linguistic authorities.
If you encounter “comprize,” it’s often a signal that the writer might be using it in a way that is not universally accepted. It’s a good practice to rephrase such sentences for clarity, even if you understand the intended meaning.
For instance, if you read, “The zoo comprized a wide variety of animals,” the intended meaning is clear: the zoo included many animals. However, a more standard and widely accepted phrasing would be, “The zoo comprised a wide variety of animals” or “The zoo included a wide variety of animals.”
Avoiding the “Comprise Of” Trap
The most frequent error associated with these words is the construction “comprise of.” This error arises from conflating “comprise” with phrases like “consist of” or “be made up of.”
Consider the sentence: “The committee comprises of five members.” This is incorrect because “comprises” already signifies inclusion. The committee *is made up of* five members, or it *consists of* five members.
The correct way to express this idea using “comprise” is: “The committee comprises five members.” The committee is the whole, and the five members are its components.
Alternatively, one could use “consists of”: “The committee consists of five members.” This construction is perfectly acceptable and often preferred for its clarity.
Alternative Phrasings for Clarity
To sidestep the potential confusion between “comprize” and “comprise,” many writers opt for alternative verbs that convey the same meaning without the grammatical nuances. These alternatives offer a clear and unambiguous way to express the relationship between a whole and its parts.
Synonyms like “include,” “contain,” “consist of,” and “be made up of” are excellent substitutes. They are widely understood and grammatically straightforward, making your writing more accessible to a broader audience.
For instance, instead of struggling with “The book comprises several chapters,” you could confidently write, “The book includes several chapters.” This sentence is clear, concise, and error-free.
Similarly, “The meal consisted of soup, salad, and a main course” is a perfectly clear and correct alternative to a potentially problematic phrasing with “comprise” or “comprize.”
“Comprise” as a Transitive Verb
The key to mastering “comprise” is to remember its function as a transitive verb. This means it requires a direct object.
In a sentence like “The team comprises talented athletes,” “talented athletes” is the direct object. The verb “comprises” acts directly upon this object, indicating that the team is made up of these athletes.
If you find yourself wanting to use “of” after the verb, it’s a strong indicator that you should consider a different verb or rephrase the sentence entirely. This is where the “comprise of” error typically occurs.
Understanding transitivity helps solidify the correct usage. The subject (the whole) performs the action of comprising upon the object (the parts).
“Comprize” in Historical Context
While modern usage leans heavily towards “comprise,” it’s worth noting that “comprize” has a history. In older English literature, you might find “comprize” used with a meaning similar to “to include” or “to contain.”
This historical usage can sometimes lead to confusion, as it differs from the more widely accepted modern definition and grammatical function of “comprise.” However, for contemporary writing, adhering to the modern standard is advisable.
If you are reading older texts, understanding that “comprize” might have a different intended meaning is helpful. But when you are writing, it is best to stick to the established and preferred forms.
Practical Application: Sentence Examples
To solidify your understanding, let’s look at several examples demonstrating correct and incorrect usage. Pay close attention to the grammatical structure and the intended meaning.
Correct: “The curriculum comprises a variety of subjects, including mathematics, science, and literature.” Here, “curriculum” is the whole, and the subjects are its components.
Incorrect: “The curriculum comprises of a variety of subjects.” The “of” is redundant.
Correct: “The exhibition comprises works from over fifty artists.” The exhibition is the whole, containing the artists’ works.
Incorrect: “The exhibition comprized works from over fifty artists.” While some might use “comprize” this way, “comprise” is generally preferred.
Correct: “The United States comprises fifty states.” The nation is made up of the states.
Correct Alternative: “The United States is made up of fifty states.” This alternative is equally clear and avoids any potential ambiguity.
A Note on “Composed Of” and “Made Up Of”
Phrases like “composed of” and “made up of” are grammatically sound and serve as excellent alternatives to “comprise.” They clearly express the idea of a whole consisting of parts without the specific grammatical rules that govern “comprise.”
For instance, “The committee is composed of five members” is perfectly correct. The subject “committee” is described as being “composed of” its members.
Similarly, “The novel is made up of three distinct parts” conveys the intended meaning clearly and effectively. These phrases offer a safe and accessible route for writers who want to ensure accuracy.
Using these alternatives can significantly reduce the likelihood of grammatical errors and enhance the overall clarity of your writing. They are universally accepted and understood.
The Role of Context and Audience
When deciding which word to use, consider your audience and the context of your writing. For academic papers, formal reports, or publications that adhere to strict style guides, using “comprise” correctly is essential.
In more informal settings, or if you are unsure about the precise application of “comprise,” opting for clearer synonyms like “include” or “consist of” is a wise choice. The primary goal of writing is to communicate effectively, and clarity should always be prioritized.
If your writing is intended for a broad audience, employing the most common and least ambiguous terms will serve you best. This ensures your message is received as intended, without any linguistic detours.
Mastering “Comprise”: The Active Voice
The active voice is where “comprise” shines. “The class comprises twenty students.” The subject “class” actively comprises the object “twenty students.”
This active construction is the most direct and standard way to use “comprise.” It emphasizes the relationship of the whole to its parts.
Avoid passive constructions that attempt to use “comprise” with “by” or other prepositions, as these often lead to awkward phrasing or errors.
The Passive Voice and “Comprised Of”
The passive voice can be a source of trouble when dealing with “comprise.” While “comprise” is transitive, some attempt to use it in a passive construction, leading to the problematic “comprised of.”
For example, “The team was comprised of the best players.” This is grammatically incorrect. The correct passive form would be “The team was composed of the best players” or “The team consisted of the best players.”
If you must use a passive-like structure, the verb “be” followed by “comprised” is not standard. Stick to “be composed of” or “be made up of” for clarity in passive constructions.
“Comprize” as a Verb Meaning “To Make Up”
In very rare instances, “comprize” might be used as a verb meaning “to make up” or “to constitute.” This usage is highly unusual and not recommended for contemporary writing.
It suggests that the parts “comprize” the whole, reversing the typical subject-object relationship seen with “comprise.” This is a significant departure from standard English grammar.
For clarity and adherence to convention, it is best to avoid this interpretation of “comprize” altogether.
The “Is Comprised Of” Fallacy
The phrase “is comprised of” is a persistent error that many writers fall into. It stems from a misunderstanding of the transitive nature of “comprise” and an attempt to use it in a way similar to “is composed of.”
The correct usage of “comprise” does not involve “of.” When you see or hear “is comprised of,” it’s almost always an indication of an error.
To correct this, either remove the “of” to create “comprises” (e.g., “The team comprises skilled athletes”) or replace “comprise” with “is composed of” or “is made up of” (e.g., “The team is composed of skilled athletes”).
Testing Your Understanding
The best way to internalize the difference is through practice. Try creating your own sentences and then review them against the rules discussed.
For example, describe your home. Does it comprise several rooms? Or does it consist of a living room, kitchen, and bedrooms?
Test yourself with various scenarios: describing a meal, a country, a book, or a project. This active engagement will reinforce the correct patterns.
The Evolution of Language
Language is not static; it evolves over time. While “comprize” might have had a more accepted role in the past, current linguistic consensus favors “comprise” and its standard grammatical functions.
Style guides and dictionaries reflect these shifts, aiming to standardize usage for clarity and consistency. Staying informed about these conventions is part of effective writing.
Adhering to established rules ensures your writing is clear and professional. It demonstrates a mastery of the language.
Final Recommendations for Writers
When in doubt, opt for clarity and simplicity. Use “comprise” as a transitive verb meaning “to consist of” or “to be made up of.”
Avoid the construction “comprise of” and the usage of “comprize” unless you are certain of its specific, albeit rare, application and audience acceptance.
Alternatively, employ synonyms like “include,” “contain,” “consist of,” or “be made up of” for guaranteed clarity and grammatical correctness.
