Quick answer: Specific means clearly defined and particular; concrete means expressed in real, tangible terms rather than abstract ideas. Give me a specific date asks for an exact one; give me a concrete example asks for a real, solid one. When in doubt: SPECIFIC = exact, not general; CONCRETE = tangible, not abstract. For a fuller definition, see the Cambridge Dictionary entry for ‘concrete’.
Comparison Table
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| specific | adjective | clearly defined, exact, particular — the opposite of general or vague | Can you be more specific about the time? |
| concrete | adjective | real, tangible, solid — the opposite of abstract | We need concrete evidence, not theories. |
Using Specific
Specific describes something exact and clearly defined, as opposed to general, broad, or vague. When you ask someone to be specific, you want precise details rather than a sweeping overview. It answers questions like which one?, exactly when?, or exactly how much?
Please give me a specific example, not a general statement.
The instructions are very specific about quantities.
Is there a specific reason you chose this design?
Each region has its own specific rules.
The opposite of specific is general or vague. Being specific narrows things down to the particular.
Using Concrete
As an adjective, concrete means real, solid, and tangible, as opposed to abstract or theoretical. A concrete idea is one you can grasp, point to, or act on — not just a vague concept. (Concrete is also a noun meaning the building material, but here we focus on the adjective.)
We need concrete proof before making accusations.
The plan is still abstract — we need concrete steps.
Can you turn that theory into a concrete proposal?
There were no concrete results from the meeting.
Concrete vs Abstract
The natural opposite of concrete is abstract. “Freedom” is abstract; “the right to vote” is concrete. When someone asks for something concrete, they want it grounded in reality, not floating in theory.
Key Differences at a Glance
- Opposite: Specific opposes general/vague; concrete opposes abstract/theoretical.
- Focus: Specific is about precision and exactness; concrete is about being real and tangible.
- Overlap: A concrete example is often also specific — but you can be specific about something abstract too.
- Extra meaning: Concrete is also a noun (building material); specific is not.
Side-by-Side Examples
Be specific: tell me the exact deadline, not just “soon.”
Be concrete: show me a working prototype, not just an idea.
She gave specific figures for each quarter.
She offered concrete suggestions instead of vague principles.
Common Mistakes
✗ Can you give me a concrete time? I need to know exactly when.
✓ Can you give me a specific time? I need to know exactly when.
✗ The theory is interesting, but we need something more specific to act on.
✓ The theory is interesting, but we need something more concrete to act on.
✗ Let’s discuss the specific of the contract.
✓ Let’s discuss the specifics of the contract. (specifics = the precise details)
Memory Tip
Think of SPECIFIC as pointing to one SPECIES — one particular kind out of many. Think of CONCRETE like the building material: solid, real, something you can touch — the opposite of an airy abstraction.

Frequently Asked Questions
What is the main difference between concrete and specific?
Specific means clearly defined, exact, and particular — the opposite of general or vague. Concrete means real, tangible, and solid — the opposite of abstract or theoretical. You ask for a specific date when you want an exact one, and a concrete example when you want a real, solid one rather than a vague idea.
Can concrete and specific be used interchangeably?
They overlap but are not identical. A “concrete example” and a “specific example” can sometimes mean the same thing, because real examples tend to be exact. But you can be specific about an abstract idea (a specific theory), and something concrete is not always narrowed to one particular case. Choose based on whether you are fighting vagueness (specific) or abstraction (concrete).
What is the opposite of each word?
The opposite of specific is general or vague. The opposite of concrete is abstract or theoretical. This contrast is the quickest way to choose: if you want to replace “vague” with “exact,” use specific; if you want to replace “abstract” with “real,” use concrete.
What are common collocations with specific?
Common collocations: specific example, specific details, specific reason, specific time, specific requirements, specific instructions, be more specific, in specific terms, a specific case, specific needs, specific information.
What are common collocations with concrete?
Common collocations (adjective sense): concrete evidence, concrete proof, concrete example, concrete steps, concrete plan, concrete results, concrete proposal, concrete action, in concrete terms, concrete facts.
Is concrete always an adjective?
No. Concrete is also a common noun meaning the building material made of cement, sand, and gravel (“a concrete floor”), and a verb meaning to cover with that material. In this comparison we focus on the adjective sense (real, tangible). Specific, by contrast, is only an adjective; its noun form is “specifics.”
What is the difference between specific and specifics?
Specific (singular adjective) describes something exact: “a specific question.” Specifics (plural noun) means the precise details of something: “Let’s discuss the specifics of the deal.” Do not use “specific” as a noun — use “specifics” or “details.”
What are the adverb forms?
The adverb of specific is specifically: “This rule applies specifically to members.” The adverb of concrete is concretely: “Let’s think about this more concretely,” meaning in real, practical terms.
Which word should I use in academic writing?
Use specific when calling for precision or narrowing a claim (“specific evidence,” “specific factors”). Use concrete when contrasting real, practical detail with abstract theory (“concrete examples support the argument”). Both strengthen academic writing when used accurately.
How do concrete and specific appear in IELTS writing?
In IELTS Task 2, examiners reward concrete examples that ground abstract claims in reality, and specific details that avoid vague generalisations. Saying “a concrete example is the rise in electric cars” or “a specific figure shows a 20% increase” both raise your lexical and task-response scores.
