Definition: Necessary vs. Necessarily
To use “necessary” and “necessarily” correctly, it’s essential to understand their definitions and grammatical functions.
Necessary
Necessary is an adjective. It describes a noun and means “required to be done, achieved, or present; essential.” It indicates something that is indispensable or cannot be done without. It answers the question, “What kind of thing is it?” or “Which thing is it?”
Examples:
- Water is necessary for survival. (Necessary describes the noun water)
- It’s necessary to have a valid passport for international travel. (Necessary describes the noun phrase to have a valid passport)
- The necessary equipment was provided by the company. (Necessary describes the noun equipment)
Necessarily
Necessarily is an adverb. It modifies a verb, adjective, or another adverb. It means “as a necessary result or condition; inevitably.” It indicates that something is a logical consequence or a certainty. It answers the question, “How?” or “To what extent?”
Examples:
- Higher prices don’t necessarily mean better quality. (Necessarily modifies the verb mean)
- If you study hard, you will not necessarily get an A. (Necessarily modifies the verb get)
- Winning the lottery does not necessarily bring happiness. (Necessarily modifies the verb bring)
Structural Breakdown
Understanding how “necessary” and “necessarily” fit into sentence structures is vital for their correct use.

- After a linking verb (e.g., be, seem, appear): The report is necessary.

“Necessarily” in Sentence Structure
As an adverb, “necessarily” usually appears:
- Before the verb it modifies: Success doesn’t necessarily depend on luck.

FAQ
Here are some frequently asked questions about “necessary” and “necessarily”:
- Q: What is the difference between “necessary” and “necessarily” in simple terms?
A: “Necessary” is an adjective that describes a noun as essential or required. “Necessarily” is an adverb that modifies a verb, adjective, or another adverb, indicating that something is a logical consequence or not guaranteed.
- Q: How can I remember which word to use?
A: Think of “necessary” as describing a *thing* and “necessarily” as describing an *action* or *quality*. If you can replace the word with “essential,” use “necessary.” If you can replace it with “inevitably” or “not always,” use “necessarily.”
- Q: Can “necessarily” ever be used at the beginning of a sentence?
A: Yes, but it’s less common. When used at the beginning, it modifies the entire clause and implies a logical consequence. For example: “Necessarily, a complex project requires careful planning.” However, rephrasing the sentence is often preferable for clarity.
- Q: Is it always wrong to use “necessary” when I mean “necessarily,” or vice versa?
A: Yes, it is grammatically incorrect. While the meaning might be understood from context, using the wrong word will make your writing sound awkward and may confuse your reader. Precise language is important for clear communication.
- Q: Are there any exceptions to the rules for using “necessary” and “necessarily”?
A: There are no true exceptions to the grammatical rules. However, idiomatic expressions or specific contexts might require careful consideration. If you are unsure, consult a dictionary or grammar guide.
- Q: Can “necessary” be used with a verb?
A: “Necessary” itself cannot directly modify a verb. However, you can use “necessary” in a phrase that includes a verb, such as “It is necessary *to study*.” In this case, “necessary” describes the infinitive phrase “to study.”
- Q: What are some synonyms for “necessary” and “necessarily”?
A: Synonyms for “necessary” include: essential, required, indispensable, vital, crucial. Synonyms for “necessarily” include: inevitably, certainly, automatically, as a matter of course, not always.
- Q: How does understanding parts of speech help me use “necessary” and “necessarily” correctly?
A: Understanding the grammatical function of adjectives and adverbs is crucial. Knowing that “necessary” is an adjective helps you remember that it describes nouns, while knowing that “necessarily” is an adverb helps you remember that it modifies verbs, adjectives, or other adverbs. This knowledge provides a solid foundation for correct usage.
