Consist IN vs Consist OF: Clear Differences with 14 Examples

Navigating the nuances of English prepositions can often feel like deciphering a complex code. Among the most commonly confused pairs are “consist in” and “consist of.” While they appear similar, their grammatical functions and the contexts in which they are used are distinct, leading to frequent errors in both written and spoken English.

Understanding these differences is crucial for clear and accurate communication. Mastering these prepositions will not only elevate your writing but also enhance your confidence when speaking the language. This guide aims to demystify these two phrases with clear explanations and illustrative examples.

Understanding “Consist Of”

The phrase “consist of” is by far the more common of the two. It is used to enumerate or list the components, parts, or elements that make up a whole entity or concept. Think of it as a way to break down something into its constituent pieces.

“Consist of” indicates that something is composed of certain things. It suggests a complete inventory of what makes up the subject. This prepositional phrase is active in describing the elements that form a larger entity.

The structure is typically: Subject + consist of + components/parts.

Understanding “Consist In”

The phrase “consist in” is less common and has a more abstract meaning. It is used to describe the essential nature, quality, or characteristic of something. It points to the fundamental principle or the defining feature that makes something what it is.

Instead of listing physical parts, “consist in” identifies the core essence or the most important aspect. It answers the question: “What is the fundamental quality or purpose of this?”

The structure is typically: Subject + consist in + quality/nature/principle.

Examples of “Consist In”

Active vs. Passive Voice

Both “consist of” and “consist in” are typically used in the active voice. While it’s grammatically possible to construct passive sentences, they are rare and often sound awkward.

For instance, you would say “The meal consists of pasta and salad,” not “Pasta and salad are consisted of by the meal.” The active voice maintains a more natural and direct flow.

This preference for the active voice makes understanding the subject-verb-object structure even more important when using these phrases.

Common Pitfalls and How to Avoid Them

The most frequent error is using “consist in” when “consist of” is appropriate, or vice versa. This usually stems from a misunderstanding of whether you are listing components or describing an essential quality.

When in doubt, ask yourself if you are enumerating the parts that make up something (use “consist of”) or if you are defining the core essence or nature of something (use “consist in”).

Another less common mistake is the overuse of “consist of” in situations where simpler verbs like “includes,” “contains,” or “is made up of” would suffice and sound more natural. While “consist of” is correct, variety in your vocabulary can enhance readability.

“Consist Of” in Different Tenses

The phrase “consist of” can be used in various tenses to describe composition at different points in time.

For example, in the past tense: “The original team consisted of only three people.” This refers to the composition of the team at a specific past time.

In the future tense, though less common, one might say: “The new system will consist of several interconnected modules.” This anticipates the future composition of the system.

The present perfect tense can also be used: “This region has always consisted of diverse ecosystems.” This indicates a composition that has been true over a long period leading up to the present.

“Consist In” in Different Tenses

Similarly, “consist in” can adapt to different tenses, though its abstract nature makes it more common in the present tense.

A past tense example might be: “In ancient times, their power consisted in their military might.” This describes the essential nature of their power historically.

Using it in the future tense is even rarer, but one could theoretically say: “The future of sustainable energy will consist in a combination of solar and wind power.” This would imply that the defining characteristic of future energy will be this blend.

The present perfect tense is more plausible: “His contribution has always consisted in offering unique perspectives.” This highlights a consistent, defining quality of his input.

Key Distinctions Summarized

The core difference lies in the type of information conveyed. “Consist of” is about enumeration and components.

“Consist in” is about essence, quality, or fundamental nature.

Think of “consist of” as a physical breakdown and “consist in” as a conceptual definition.

When to Use “Comprise” Instead

The verb “comprise” is often used interchangeably with “consist of,” but there are subtle differences and grammatical conventions to observe.

“Comprise” means to consist of or be made up of. A key rule often cited is that “comprise” is used actively: “The whole comprises its parts.” Thus, “The United States comprises fifty states.”

Conversely, “consist of” is used passively in relation to its parts: “The United States consists of fifty states.” The parts comprise the whole, and the whole consists of the parts.

While “comprise of” is considered incorrect by many prescriptivists, it is increasingly common in informal speech. However, for formal writing, sticking to “comprises” (active) or “is comprised of” (passive, though some also dislike this) is advisable.

Nuances in Figurative Language

Both phrases can be used figuratively, but “consist in” lends itself more readily to abstract or philosophical statements.

For instance, “The true meaning of courage consists in acting despite fear.” This is a figurative use, defining the essence of courage.

“Consist of” can also be used figuratively, but it often retains a sense of listing elements, even if those elements are abstract. “His apology consisted of empty words and insincere promises.” Here, the components of the apology are listed.

The distinction remains: “consist in” defines the core quality, while “consist of” enumerates the constituent parts, even when used metaphorically.

Grammatical Structure and Word Order

The grammatical structure is a fundamental differentiator. “Consist of” is followed directly by the nouns or noun phrases that represent the components.

For example, “The meal consists of three courses.” The phrase “three courses” directly follows “consist of.”

“Consist in” is followed by a noun, noun phrase, or gerund that describes the essential nature or quality.

For instance, “His talent consists in his ability to improvise.” The phrase “his ability to improvise” follows “consist in.”

Why the Confusion Persists

The confusion between “consist in” and “consist of” often arises because both phrases relate to what something is made of or what defines it.

The subtle difference between listing physical or conceptual parts versus defining an essential quality can be easily overlooked, especially in everyday conversation where precision may be less critical.

Furthermore, the relative rarity of “consist in” compared to “consist of” means many speakers and writers encounter it less frequently, leading to uncertainty about its correct application.

Advanced Usage and Context

In academic or philosophical writing, “consist in” is more likely to appear when defining abstract concepts or principles.

For example, “The ethical framework consists in a commitment to fairness and impartiality.” This defines the core principles of the framework.

“Consist of,” while also used in academic contexts, will typically be found when detailing structures, components, or ingredients, even in abstract subjects.

“The research methodology consists of a qualitative survey followed by quantitative analysis.” This outlines the steps or components of the methodology.

Practical Application in Writing

When writing, always pause to consider the exact meaning you wish to convey.

If you are breaking something down into its constituent elements, “consist of” is your choice. If you are defining the fundamental nature or essence, “consist in” is the correct preposition.

Practicing with sentences and consciously choosing the right phrase will solidify your understanding and improve the clarity of your writing.
