'kind/type/sort of a/an'

Writers often add an unnecessary article after phrases like kind of, type of, or sort of-e.g., "a kind of a bird." That extra a/an is usually redundant and makes sentences clumsy.

The sections below show when the extra article is incorrect, when casual speech differs, and how to rewrite sentences for work, school, and everyday writing.

Quick answer

Don't put a/an between of and the noun after kind/type/sort of. Say "a kind of bird," not "a kind of a bird."

• Use: kind/type/sort of + noun → no article after of (a kind of plant, a type of error).
• Adverbial use (I'm kind of tired) never takes an article either.
• If removing the article leaves the sentence awkward, rewrite for clarity.

Core explanation (short): why the extra article is redundant

Kind of, type of, and sort of function as classifiers. They link the noun to its category, so inserting a/an repeats the determiner and creates redundancy.

Standard pattern: [a/an] + kind/type/sort + of + NO article + noun. Example: "a kind of bird."

• Wrong: I saw a kind of a bird. →
  Right: I saw a kind of bird.
• Wrong: She's a type of a leader. →
  Right: She's a type of leader.
• Simple correction: Wrong: I found a sort of a solution.
  Right: I found a sort of solution.

Grammar details to watch for

Countability: The rule applies regardless of countability-use "a kind of fruit," "a type of evidence." If the noun needs an article for another reason, rephrase.

Adjective + noun: Put the article with the adjective and noun, not between of and noun. Prefer "an unusual kind of problem" over "a kind of an unusual problem."

• If you mean "one subclass of many," use: a kind of X (no extra article).
• If kind of = somewhat (adverb), it's not followed by an article: "I'm kind of tired."
• Adjective placement: Better: an unusual kind of problem. (Not: a kind of an unusual problem.)

Hyphenation and spacing: kind-of vs kinda and compound modifiers

Do not hyphenate "kind of" when it directly precedes a noun: write "a kind of solution." Hyphenate only if the entire phrase is forced into a compound adjective (rare): "a kind-of-moment"-but a rewrite is usually clearer.

"Kinda" is an informal contraction of "kind of" used in speech and casual writing; avoid it in formal contexts.

• Correct spacing: a kind of solution
• Avoid: a kind-of solution (prefer: a kind of solution or this kind of solution)
• Casual: "He's kinda tired."
  Formal: "He is somewhat tired."

Real usage: formal vs informal choices

Formal writing: remove the extra article and prefer precise words (category, variety, species, class, version).

Informal speech: "a kind of a" sometimes appears for emphasis or rhythm. That idiom can be acceptable colloquially, but it is nonstandard in careful writing and often signals a different meaning (somewhat a label).

• Formal: "a type of analysis" (not "a type of a analysis").
• Informal idiom: "He's kind of a perfectionist." (colloquial-means somewhat a perfectionist)

Rewrite help: step-by-step repairs and multiple rewrites

Spot "kind/type/sort of a/an" and do two things: remove the extra article; if it still sounds off, apply one of the rewrite patterns below.

• Repair patterns: (a) Drop the extra article: "a kind of X". (b) Move the adjective: "an unusual kind of problem". (c) Replace with a stronger noun/verb: "I noticed a problem with the code."
• For formal tone, swap in precise nouns: category, variety, species, class, version.

• Rewrite-1: Wrong: I saw a kind of a problem with the code. → Drop article: I saw a kind of problem with the code. → Stronger: I noticed a problem with the code.
• Rewrite-2: Wrong: They're a type of a expert in vintage cars. → Drop article: They're a type of expert in vintage cars. → Clearer: They're experts in vintage cars.
• Rewrite-3: Wrong: She had a sort of a look that told me she was upset. → Drop article: She had a sort of look that told me she was upset. → Shorter: She looked upset.
• Rewrite-4: Wrong: We found a sort of a pattern in the data. → Drop article: We found a sort of pattern in the data. → Precise: We found a recurring pattern in the data.
• Rewrite-5: Wrong: He plays a kind of a role in the project. → Drop article: He plays a kind of role in the project. → Better: He plays a supporting role in the project.
• Rewrite-6: Wrong: This is a kind of a test we haven't done. → Drop article: This is a kind of test we haven't done. → Better: This is a test we haven't conducted before.

Quick checklist: fix your sentence in 30 seconds

Proofread with these three steps to fix the error fast.

• 1) Find kind/type/sort of. 2) If an a/an follows of, delete it. 3) Read aloud; if it still sounds odd, rewrite using a stronger noun or different word order.
• Checklist example: Draft: "We discovered a sort of a pattern." → Remove article: "We discovered a sort of pattern." → Better: "We discovered a pattern."

Memory tricks and quick rules to remember

Use quick mental checks rather than long rules: if you can substitute "category" or "type" and it reads fine, you don't need the extra article.

• Read aloud with and without the article-if the version without it sounds natural, keep it.
• Mnemonic: "of already = one of" → you don't need another article.
• Rule of thumb: never put a/an between of and the noun.

Similar mistakes and related pitfalls

Small edits can change meaning or register. Watch these related traps.

• Don't confuse "a kind" (a nice person) with "a kind of" (a category).
• "Kind of a" before a label can be idiomatic: "kind of a nerd" is colloquial and different from classifier + noun.
• Example: Wrong: He's a kind of a nice guy. (awkward) →
  Right: "He's kind of a nice guy." (informal: somewhat nice) or "He's a kind guy." (he is nice).
• Other error: "one of a people" → Right: "one of the people" or "a member of the group."

FAQ

Is "kind of a" always wrong?

Not in speech. In careful writing, an article after of is redundant and usually wrong. In casual idioms ("kind of a nerd") it's acceptable but conveys a different, colloquial meaning.

Should I always remove a/an after kind/type/sort of?

Yes for classifier + noun constructions: use kind/type/sort of + noun with no intervening article. If removal makes the sentence awkward, rewrite instead of keeping the extra article.

Can "kind of" mean "somewhat"? Does that use take an article?

When "kind of" means "somewhat" (adverbial), it doesn't take an article: "I'm kind of tired." That is distinct from the classifier construction.

What if the noun needs its own article for another reason?

Restructure the phrase: instead of "a kind of a very unusual problem" write "an unusual kind of problem" or simply "a very unusual problem."

How can I catch these quickly in drafts?

Search for "kind of", "type of", and "sort of" and look for an immediate a/an after of. Reading aloud helps; a lightweight grammar checker can flag the pattern and suggest rewrites.
