Like vs Such As — What’s the Difference?

Like introduces a comparison, suggesting similarity without inclusion. Such as introduces specific examples that are part of the group being discussed. The key difference: like means “similar to” (the items mentioned are not necessarily included), while such as means “for example” (the items mentioned are included). This distinction matters most in formal and academic writing, where precision is expected.

Why Getting This Right Matters

Confusing like and such as may seem minor, but in formal writing it can introduce real ambiguity. In a medical report, “allergens like peanuts” could be read as allergens similar to peanuts rather than peanuts themselves — a dangerous misreading when patient safety is at stake. In academic papers, imprecise language weakens your credibility with reviewers. And in business proposals, unclear example lists can lead to contractual misunderstandings. Mastering this small distinction signals careful, professional command of English.

What Does “Like” Mean?

When used as a preposition before a noun, like means “similar to” or “resembling.” It draws a comparison between two things without necessarily including the named item in the category. “A city like Paris” could mean a city that resembles Paris in some way, such as Rome or Barcelona, but Paris itself may or may not be included in the discussion.

This comparative function is the traditional use that grammarians distinguish from such as. The AP Stylebook maintains this distinction, advising writers to use like for comparisons and such as for examples. However, in everyday speech and informal writing, like routinely introduces examples: “I enjoy fruits like apples and oranges.” Most readers understand this to mean apples and oranges are examples, not that the speaker enjoys fruits similar to but different from apples and oranges.

Like has many other functions in English, including as a verb (“I like coffee”), an adverb (“It was, like, amazing”), and a conjunction in informal speech (“It looks like it might rain”). For the purpose of the like-vs-such-as debate, we are focused on the prepositional use meaning “similar to.”

Etymologically, the prepositional use of like derives from Old English gelic, meaning “similar” or “having the same form.” Its long history as a comparison word is why traditional grammarians insist on reserving it for similarity rather than exemplification. The debate over whether like can introduce examples has been active since at least the mid-20th century, when usage commentators began noting that the strict distinction was eroding in spoken English while persisting in edited prose.

What Does “Such As” Mean?

Such as introduces specific examples that belong to the category being discussed. “European cities such as Paris, Rome, and Berlin” names three cities that are definitively part of the group of European cities. There is no ambiguity about inclusion; the named items are examples drawn from the larger set.

In formal writing, such as is the preferred choice when listing examples. Academic papers, legal documents, and business reports rely on such as to signal that what follows is a representative list, not a comparison to external items. “Renewable energy sources such as solar, wind, and hydroelectric power” makes clear that solar, wind, and hydro are types of renewable energy, not things resembling renewable energy.

Such as can introduce a restrictive list (essential to the sentence’s meaning) or a nonrestrictive list (supplementary information). With a comma, “Countries, such as Japan and Germany, have invested heavily in rail” treats the examples as a parenthetical aside. Without a comma, “Countries such as Japan and Germany have invested heavily in rail” restricts the statement to those specific countries. This comma placement changes the scope of the sentence.

Key Differences Between Like and Such As

Inclusion vs similarity. This is the traditional distinction. Such as includes the named items as examples of the category. Like compares without necessarily including. “Teachers like Mrs. Johnson” might mean teachers similar to Mrs. Johnson but not Mrs. Johnson herself. “Teachers such as Mrs. Johnson” means Mrs. Johnson is one of the teachers in question.

Formality. Such as is more formal and precise. Like is more conversational and versatile. In academic, legal, and professional writing, such as is the safer choice when introducing examples. In casual emails, blog posts, and everyday speech, like is natural and widely accepted.

Style guide positions. The AP Stylebook distinguishes between the two, reserving like for comparisons and such as for examples. The Chicago Manual of Style is more permissive, noting that like is commonly used to mean such as and that context usually prevents confusion. Garner’s Modern English Usage also recognizes the distinction while acknowledging that it is eroding in informal usage.

Ambiguity potential. In most contexts, the difference is negligible. But in precise writing, the distinction can matter. “Allergens like peanuts” could theoretically mean allergens resembling peanuts (tree nuts?), while “Allergens such as peanuts” unambiguously lists peanuts as an example. In medical, scientific, or legal writing, this precision can be important.

The linguistic WHY. This is a semantic-overlap pair, not a homophone pair — the words sound nothing alike, but their functions partially overlap in modern English. The confusion stems from a historical shift: like originated strictly as a comparison word (from Old English gelic, “similar in form”), but over centuries its meaning drifted to include exemplification, encroaching on territory that such as had occupied. The AP Stylebook preserves the older, stricter boundary; the Chicago Manual of Style (17th edition, section 5.220) accepts the broader modern usage. This is one of the few word-pair debates where the “correct” answer depends on which style guide your editor follows.

Like vs Such As — Examples in Context

Using “such as” for examples: Programming languages such as Python, JavaScript, and Rust are in high demand.

Using “like” for comparison: A programming language like Python makes scripting accessible to beginners. (Comparing to Python’s characteristics.)

Correct (formal): Chronic conditions such as diabetes and hypertension require ongoing management.

Less precise: Chronic conditions like diabetes and hypertension require ongoing management. (Acceptable informally, but could theoretically mean “similar to.”)

Correct: Some animals, such as dolphins and elephants, demonstrate high intelligence.

Correct: She wanted a pet like a golden retriever: friendly, loyal, and energetic. (Comparing qualities.)

Correct: Platforms such as LinkedIn and Indeed are popular for job searching.

Correct: He built a platform like LinkedIn for niche professional communities. (Comparing to LinkedIn.)

Correct: Minerals such as iron and calcium are essential for bone health.

Correct: A city like New York never truly sleeps. (Comparison: New York or places with its characteristics.)

Correct: Cities such as New York and Tokyo are global financial hubs. (Examples.)

Correct: Benefits such as health insurance and retirement plans attract top talent.

Ambiguous in formal writing: Benefits like health insurance and retirement plans attract top talent.

Common Mistakes and How to Avoid Them

The most common mistake is using like in formal contexts where such as would be more precise. In a research paper, “nutrients like vitamin C” could technically refer to nutrients similar to vitamin C rather than vitamin C itself. While context usually resolves this, such as eliminates the ambiguity entirely.

Another mistake is overusing such as in conversational writing, which can make the text sound stiff. In a casual blog post, “I love cuisines such as Thai, Indian, and Mexican” sounds overly formal. “I love cuisines like Thai, Indian, and Mexican” fits the tone better. Match the formality of the phrase to the register of your writing.

Some writers use “such as” and follow it with “etc.” or “and so on.” This is redundant; such as already implies the list is not exhaustive. “Fruits such as apples, bananas, etc.” should be “Fruits such as apples and bananas” or “Fruits like apples, bananas, and others.” BeLikeNative can help flag these small redundancies and word-choice issues as you type.

Watch out for the phrase “and things like that” as a spoken filler. In writing, replace vague trailing phrases with a clear such as list. Instead of “We need office supplies and things like that,” write “We need office supplies such as printer paper, toner, and folders.” This transforms a vague statement into a precise one and demonstrates stronger command of written English.

The #1 mistake pattern: The error surfaces most in sentences that list concrete items after a category noun — “skills like leadership,” “tools like Excel,” “languages like Spanish.” In every case, the writer means these specific items, not items resembling them. If your list is meant to exemplify, switch to such as in any document that will be formally reviewed.

Non-native speaker angle: Speakers of East Asian languages (Chinese, Japanese, Korean) often find this distinction especially confusing because their languages typically use a single particle or phrase for both comparison and exemplification. Mandarin’s “像” (xiàng) and “比如” (bǐrú) map roughly onto like and such as, but the boundary between them is far less rigid, making the English distinction feel artificial at first.

Quick Memory Trick

Such As = Specific Actual examples (the items ARE in the group). Like = Likeness (the items RESEMBLE the group). If the items you name are real members of the category, use S.A. — such as. If you are pointing to something similar for comparison, use like. “Instruments such as the violin” = the violin IS one. “An instrument like the violin” = something similar to it.

FAQ

Is it wrong to use “like” instead of “such as”?
In casual writing and speech, no. Most readers understand “like” to mean “for example.” In formal writing, such as is more precise and avoids potential ambiguity about whether the items are included or merely compared.

Do all style guides distinguish between like and such as?
No. The AP Stylebook maintains the distinction. The Chicago Manual of Style acknowledges the traditional rule but notes that like is widely accepted for examples. Garner’s recognizes the distinction while tracking its erosion.

Can I use “such as” in casual writing?
Yes, but it may sound more formal than necessary. In emails, social media posts, and conversational blog writing, like often sounds more natural.

Is “such as” followed by “etc.” correct?
It is redundant. Such as already signals that the list is not complete. Drop the “etc.” and let such as do the work.

Does a comma go before “such as”?
It depends. Without a comma, the list is restrictive (essential): “Countries such as Japan invest in rail.” With a comma, the list is nonrestrictive (supplementary): “Countries, such as Japan, invest in rail.” The comma changes whether the sentence applies broadly or only to the named examples.
