Quick Answer
Comprise means “to be made up of” or “to consist of,” and the whole is its subject: the team comprises five players. Compose means “to make up” or “to form,” and the parts are its subject: five players compose the team. Because comprise already means “consist of,” the common phrase comprised of is widely regarded as incorrect; use composed of or simply comprises instead.
Compose and comprise both describe the relationship between a whole and its parts, which is exactly why they are so easily confused. The trick is that they point in opposite directions. With comprise, the whole comes first and contains the parts. With compose, the parts come first and build the whole. Getting the direction right — and avoiding the trap of “comprised of” — is the heart of using this pair correctly.
At a Glance: Compose vs Comprise
| Word | Part of Speech | Pronunciation | Core Meaning |
|---|
| compose |
verb |
/kəmˈpoʊz/ |

| comprise |
verb |
/kəmˈpraɪz/ |
to consist of; to be made up of (whole → parts) |
Using “Compose”
Compose means to make something up out of parts, or to create a piece of music, writing, or art. When it describes structure, the parts are the subject and they compose the whole. It very commonly appears in the passive: the whole is composed of its parts.
When to use it
- The parts forming the whole: fifty states compose the USA
- Passive structure (very common): water is composed of hydrogen and oxygen
- Creating music or writing: she composed a symphony
- Arranging something carefully: compose a photograph, compose yourself
- Related words: composer, composition, composure
The committee is composed of seven members.
Sixty pieces compose the entire jigsaw.
Mozart composed over six hundred works.
Take a moment to compose yourself before you speak.
The novel is composed of twelve interlocking stories.
Using “Comprise”
Comprise means to consist of or to be made up of. The whole is the subject, and the parts follow directly with no preposition: the house comprises four rooms. Crucially, you should not say “is comprised of” — that mixes the comprise pattern with the compose pattern.
When to use it
- The whole listing its parts: the course comprises ten modules
- Formal descriptions of contents: the collection comprises rare manuscripts
- Avoid the preposition: say comprises ten units, not comprises of ten units
- Avoid the passive: prefer comprises or is composed of, not is comprised of
- Related noun: there is no smooth noun form; use composition for the structure
The United Kingdom comprises four countries.
The anthology comprises forty short poems.
Our department comprises twelve full-time staff.
The estate comprises a manor house and three cottages.
The syllabus comprises grammar, vocabulary, and writing.
The Key Difference
The key is direction. Comprise goes whole → parts: the larger thing is the subject, and it lists what it contains (the team comprises five players). Compose goes parts → whole: the smaller things are the subject, and they build the larger thing (five players compose the team). Because comprise already includes the meaning “of,” the phrase comprised of doubles up and is treated as an error in careful writing — use composed of instead.
Memory Tip
Remember: “the whole comprises the parts; the parts compose the whole.” If you can swap in “consists of,” the right word is comprises (with no “of” after it). If you can swap in “make up” or “is made up of,” use compose / is composed of. And never write “comprised of.”

Frequently Asked Questions
What is the difference between compose and comprise?
Compose means to make up or form a whole, and the parts are its subject: fifty states compose the country. Comprise means to consist of or be made up of, and the whole is its subject: the country comprises fifty states. The simplest summary is that the whole comprises the parts, while the parts compose the whole. They describe the same relationship but from opposite directions, which is why writers mix them up. If you can substitute consists of, use comprise; if you can substitute make up, use compose.
Is 'comprised of' correct?
In careful, formal English, comprised of is widely treated as an error. The verb comprise already means to consist of, so comprised of effectively says is consisted of, which is redundant. Instead, use composed of (the book is composed of three parts) or use comprise on its own with no preposition (the book comprises three parts). Although comprised of is extremely common in everyday writing, editors, examiners, and style guides usually correct it, so it is safest to avoid it.
Does comprise take 'of' after it?
No. Comprise should be followed directly by its parts, with no preposition: the kit comprises a tent, a stove, and a map. Writing comprises of is incorrect because the of is already built into the meaning of comprise. If you feel you need the word of, that is a signal you should switch to composed of instead, which is the correct pattern: the kit is composed of a tent, a stove, and a map.
Which comes first, the whole or the parts?
It depends on the verb. With comprise, the whole comes first as the subject and the parts follow: the orchestra comprises eighty musicians. With compose, the parts come first as the subject and the whole follows: eighty musicians compose the orchestra. So the two verbs let you describe the same fact in opposite orders. Choosing the right one mainly means checking which element you have made the subject of your sentence.
Can compose mean to write music?
Yes. One of the most common meanings of compose is to create a piece of music, writing, or art: Beethoven composed nine symphonies; she composed a thoughtful reply. This sense gives us composer (someone who writes music) and composition (a created work). Comprise has no such meaning; it only describes what something consists of. So if you are talking about creating something, compose is always the right verb, never comprise.
What does 'compose yourself' mean?
To compose yourself means to make yourself calm and in control again after being upset, nervous, or excited: she took a deep breath and composed herself before the interview. This sense connects to composure, the noun for calm self-control. It uses compose, not comprise, because it is about arranging or settling your feelings into order. Comprise is never used this way; it only refers to the parts that make up a whole.
Is comprise more formal than compose?
Comprise tends to sound more formal and is common in legal, technical, and official writing, such as property descriptions (the estate comprises a house and two barns) or course outlines (the programme comprises four modules). Compose, especially in the form composed of, is slightly more neutral and works well in both formal and everyday writing. Both are correct in formal contexts; the main thing is to keep the whole-to-parts direction right and to avoid comprised of.
How do I rewrite 'is comprised of'?
You have two clean options. First, switch to is composed of, keeping the whole as the subject: the report is composed of five chapters. Second, drop the passive and use comprises directly: the report comprises five chapters. Both are correct and mean the same thing. Choose composed of if you want to keep a passive, of-style structure, and comprises if you prefer a tighter active sentence. Either way, you avoid the disputed comprised of.
Can I use 'consist of' instead?
Yes, consist of is a very useful, always-correct alternative that sidesteps the whole confusion. It works exactly like comprise in terms of direction (whole first, parts after) but always takes of: the meal consists of three courses. Because it never causes the comprised of problem, many writers prefer consist of when they are unsure. So if compose and comprise feel risky, consist of is a safe, natural choice that readers will never question.
Are compose and comprise related to 'composition'?
Composition is the noun most closely tied to compose. It can mean a created work (a musical composition) or the way parts are arranged to form a whole (the composition of the committee). Comprise does not have a smooth, everyday noun form of its own, so when you need a noun for what something is made up of, composition is usually the word you reach for. Composure, meaning calm self-control, is also part of the compose family, not the comprise family.
