Is Like A Conjunction? | What Like Does In English

You hear it all day: “It’s like he forgot,” “I was like, ‘No,’” “This tastes like oranges.” The word like is everywhere, and it often appears right before a full clause. That placement makes it feel like a joining word, so the question is fair.

English grammar has two tracks here. Traditional classroom rules give tidy categories. Real usage in speech is looser. This article shows where like sits in standard grammar, why it can feel conjunction-ish, and how to choose the safest wording for school and formal writing without sounding stiff.

Is Like A Conjunction? A clear answer for writers

In standard grammar, like is usually not classed as a conjunction. It most often works as a preposition meaning “similar to,” and it is followed by a noun phrase: “She sings like her sister.”

People also use like before a clause: “She sings like she owns the stage.” Many readers accept that sentence with no trouble. Still, many teachers and editors prefer as, as if, or as though before a full clause in formal prose. That preference is why you may see red marks on “like + clause” in assignments.

So, if you need a one-line rule for careful writing: use like before nouns and noun phrases; use as, as if, or as though before clauses. If you are writing dialogue or a relaxed personal voice, “like + clause” can fit, as long as the sentence stays clear.

What makes a word a conjunction

A conjunction links grammatical units. Some link equals; some link a dependent clause to a main clause. The label matters because it predicts how the word behaves with punctuation and sentence structure.

Coordinating conjunctions

These join items of the same type: word to word, phrase to phrase, clause to clause. In English, the set is small. A classic test is that each side could stand in the same slot in the sentence: “tea and coffee,” “ran but smiled,” “call or text.”

Subordinating conjunctions

These introduce a dependent clause: “I left because it was late,” “Call me when you arrive.” The dependent clause adds meaning but relies on the main clause. Subordinators also signal the kind of link: reason, time, condition, contrast, and so on.

Where “like” sits in standard grammar

Like is a shape-shifter. The same spelling shows up in several roles, and the role changes based on what follows it. When you classify it, don’t guess from vibe. Check the structure right after the word.

Like as a preposition

This is the most common role. Like means “similar to,” and it is followed by a noun phrase: “He drives like my uncle,” “The room smells like smoke.” In these sentences, like does not join two clauses. It links a clause to a comparison phrase.

Like as an adverb in informal speech

In conversation, like can sit near a number or a description and signal approximation: “It took like ten minutes.” Here, it does not connect clauses; it softens the precision of the claim.

Like as a discourse marker

People use like to manage speech: to pause, to repair a sentence mid-stream, to signal a quote, or to show stance. “I was like, ‘Stop.’” This pattern is common in speech and in writing that intentionally mirrors speech. In an academic paragraph, editors often cut it.

When “like” acts conjunction-ish

The debate starts when like is followed by a clause with a subject and a verb: “It seems like she knows.” The clause feels like a unit being introduced, which is the job people associate with subordinating conjunctions.

Many modern descriptions of English note that this pattern is widespread and stable. Some usage guides accept it in many contexts. Many teachers still prefer as if or as though in formal writing, partly because it keeps the older category lines neat.

Why the clause pattern bothers some editors

A traditional rule says a preposition takes an object, and the object is usually a noun phrase. A finite clause is not a noun phrase, so “preposition + finite clause” feels off to people trained on that rule.

A practical way to spot the pattern

Check what comes after like:

• If it’s a noun phrase, the sentence matches the standard preposition pattern: “She runs like the wind.”
• If it starts with a subject and verb, it’s the clause pattern: “She runs like she’s late.”

Both are understandable. Only the second tends to trigger style feedback in formal settings.

How to choose between “like” and “as” without second-guessing

You can make the choice mechanical. Decide what you need to follow the connector.

• Noun phrase after the connector: use like. “He talks like a teacher.”
• Clause after the connector: in formal writing, use as, as if, or as though. “He talks as if he knows the answer.”
• Dialogue or casual tone: “like + clause” can fit. Keep the clause short and clear: “He talks like he knows the answer.”

If you want a plain set of examples with labels, the Cambridge Dictionary entry for “like” lists common meanings and patterns with real sentences.

Common “like” patterns that trip up learners

Many learners meet “like + noun” early. Later they hear “like + clause,” then they see “be like + quote,” and it starts to feel as if one word is breaking rules. The trick is to treat each pattern as its own template.

Pattern 1: Like + noun phrase

This is the safest structure across settings. It expresses similarity and rarely draws objections.

• “This fabric feels like silk.”
• “She looks like her aunt.”

Pattern 2: Feel like + -ing form

“I feel like going home.” Here, “going home” works like a noun chunk that names an activity. That keeps the structure close to the preposition pattern. In formal prose, you can keep it, or you can rephrase: “I want to go home.”

Pattern 3: Like + clause

“I feel like I should call.” This is the pattern that can get flagged in school writing. A close formal rewrite is “I feel as if I should call.” If you use “like + clause” in polished writing, do it with purpose and keep it sparing.

Pattern 4: Be like + quote

“She was like, ‘Stop.’” This frames a quote in a conversational way. It can show character voice and timing in dialogue. In reports and essays, many writers switch to “said,” “asked,” or “replied.”

Table of “like” roles with safe rewrites

This table maps common roles of like to what follows it and an edit you can use when you want a stricter tone.

Role of “like”	What follows	Safer rewrite for formal prose
Similarity preposition	Noun phrase (“like my brother”)	Keep “like”
Clause introducer	Finite clause (“like he forgot”)	Use “as if / as though”
Feeling + activity	-ing form (“like going home”)	Use “want to” when it fits
Approximation	Number or measure (“like ten minutes”)	Use “about”
Quote frame	Direct speech (“was like, ‘…’”)	Use “said / asked / replied”
Pause marker	Comma-set filler (“It was, like, odd”)	Delete it
Fixed adjective use	Noun (“like minds”)	Use “similar” when it reads better
Set phrase	Idiom (“like-for-like”)	Keep the term

How teachers and editors usually grade it

School rules favor consistency: “Use like before nouns; use as before clauses.” That keeps academic writing in the safest lane.

The Merriam-Webster note on “like” and “as” gives a clear history of the rule and shows how modern usage is treated in many contexts.

Sentence-level moves that keep your grammar tidy

Use “as if” when the clause after “like” is long

Long clauses can make the sentence feel loose. “As if” often makes the link feel tighter: “It sounded as if the engine was struggling on the hill.”

Keep “like” for direct comparisons

When you compare one thing to another thing, like is clean: “The clouds looked like cotton.” That pattern is standard.

Trim “like” as a pause word during revision

If you see “like” sprinkled as a pause marker, cut most of them. Leaving one in dialogue can show timing and attitude. Leaving many in expository writing can distract.

These pairs keep the meaning while shifting the tone. Use them as templates when you revise.

Casual sentence	More formal rewrite	Change made
It looks like it’s going to rain.	It looks as if it’s going to rain.	Clause marker swapped
I feel like I should email her.	I feel as if I should email her.	Clause marker swapped
He was like, “No.”	He said, “No.”	Quote frame swapped
It was like ten minutes.	It was about ten minutes.	Approximation word swapped
She talks like she knows everything.	She talks as if she knows everything.	Clause marker swapped
That sounds like you’re upset.	That sounds as though you’re upset.	Clause marker swapped

What to do when you’re writing for mixed audiences

Some writing sits between formal and casual: blog posts for learners, class message boards, school newsletters, or professional emails to people you know. In those settings, the safest plan is to keep like for noun-phrase comparisons and use “as if / as though” for clauses. It reads natural, and it avoids the red-pen debate.

When you write dialogue, quotes, or personal voice, you can keep “be like” and “like + clause” if that matches how the character or speaker sounds. Use it with restraint, and keep the sentence structure clear so the reader never has to reread.

Try this final check during revision: remove like from the sentence. If the meaning breaks, the word is doing real work and you should keep it or replace it with “as if” or “about.” If the meaning stays the same, it was filler, and cutting it will make the line sharper.
