Is However A Subordinate Conjunction? | Usage Rules Guide

When students meet the word however in class, online exercises, or exams, the label that follows often feels confusing. Different books call it an adverb, a conjunction, a connector, or even a subordinate conjunction. That mix of terms can make it hard to know what to write in tests or how to punctuate real sentences.

What Subordinate Conjunctions Do In A Sentence

Before you decide whether however belongs in the group, it helps to see what subordinate conjunctions actually do. A subordinating conjunction introduces a dependent clause and links it to a main clause. The clause that follows cannot stand alone as a complete sentence, because it relies on the main clause for full meaning.

Connector Type	Main Role	Typical Words
Subordinating conjunction	Introduces a dependent clause	because, if, when, since, while, before, after
Conjunctive adverb	Links two sentences or clauses	the word in this article and other linking adverbs
Coordinating conjunction	Joins equal units	and, but, or, nor, so, for, yet
Relative pronoun	Introduces a relative clause	who, which, that
Relative adverb	Introduces a relative clause with time, place, or manner	when, where, why, however
Sentence adverb	Comments on the whole sentence	sadly, fortunately, frankly
Linking phrase	Connects ideas across sentences	for that reason and related phrases

Linguists often reserve the label subordinator for a small, closed list of words such as that, whether, if, and for in specific patterns. That list rarely includes the word however.

Is However A Subordinate Conjunction Or Something Else?

The short classroom answer to the question is however a subordinate conjunction? is no. Most current grammar references treat it as an adverb that connects ideas, not as a member of the core subordinating conjunction set. Resources such as the Cambridge Dictionary entry for “however” list it as an adverb that can function as a connector between clauses.

In many style guides you will also see the label conjunctive adverb. A conjunctive adverb links two sentences or two independent clauses and shows a relation such as contrast, result, or time. Resources from university writing centers and handbooks regularly place however in this group.

So while some teaching sites loosely call it a subordinating conjunction, it behaves in a different way. It does not turn the clause that follows into a dependent clause in the same way that words such as because or if do. Instead it keeps both sides as full clauses and signals the contrast between them.

Why Grammars Call However A Conjunctive Adverb

To see this pattern, look at a pair of sentences such as:

The train was delayed. However, we still arrived on time.

Each part stands as a complete sentence. You can join them with a full stop plus capital letter, or with a semicolon plus the connector, as guides from major writing centers explain. In either case the two clauses remain independent; the connector simply marks contrast.

If you tried to treat this as a standard subordinate conjunction, you would expect a pattern such as subordinator + subject + verb, where the clause could move before or after the main clause. That pattern does not match the way the word works when it links two full sentences of contrast.

Relative Clause Pattern With However

There is one pattern where the word does introduce something that behaves like a dependent clause. It appears in sentences such as:

However you look at it, the timetable is confusing.

Here, many grammarians call the word a relative adverb in a fused relative construction. The idea is close to in whatever way. The clause however you look at it cannot stand on its own and depends on the main clause for full meaning.

The main point for learners is that exams rarely test this subtle label. They test whether you can use the structure correctly and recognise the meaning of contrast or manner.

How Teachers Classify However In Academic Writing

Many students worry about giving the wrong label in essays, quizzes, or teacher conferences. In most school and university settings you can safely describe the word as a conjunctive adverb or as a linking adverb. That phrasing matches how large teaching sites and academic writing centers describe it.

So when this question about the status of the word appears in your notes, you can respond along these lines in class:

• It does not behave like a typical subordinating conjunction such as because or if.
• Most current references list it as a conjunctive adverb or linking adverb.
• It can also work as a relative adverb in patterns like however you do something.

If your teacher or textbook tells you to group it with subordinating conjunctions for a particular exercise, that choice usually reflects a simplified classroom model. For real writing and later study, the adverb label lines up better with modern reference works.

How To Use However Between Independent Clauses

Getting the punctuation right matters more for grades than the label on a chart. Many learners place a comma before the word and forget to mark the break between two independent clauses. University writing guides treat that pattern as a comma splice and mark it as an error.

To avoid that problem when you write, follow this basic procedure:

1. Write the first clause as a full sentence with a clear subject and verb.
2. End that clause with either a full stop or a semicolon.
3. Begin the next clause with a capital letter if you used a full stop.
4. Place the word however at the start of the new clause or after the subject.
5. Add a comma after the word.
6. Finish the second clause as a complete sentence.

Here is a model using a semicolon:

The experiment looked simple; however, the results were hard to interpret.

Here is a model using a full stop:

The experiment looked simple. However, the results were hard to interpret.

Both structures match advice from style guides and avoid the comma splice that teachers often underline.

How To Use However Inside A Clause

The word does not need to sit at the start of a sentence. You can place it inside a clause to mark contrast between two parts of the same idea. In that case it usually appears between commas.

Consider this sentence: The research method, however, takes more time than the summary suggests.

The commas signal that the word comments on the clause rather than attaching tightly to a single verb. If you removed it, the sentence would still stand as a complete statement. With it, the sentence now shows a mild turn in thought.

Many academic style guides ask writers not to overuse this pattern. When every sentence begins with the same connector, the writing feels heavy and repetitive.

Comparing However With Subordinate Conjunctions

To fix the idea in long term memory, it helps to compare the word with more typical subordinating conjunctions. Look at these pairs of sentences and notice how the structure changes:

We stayed in the lab because the report was due.
The report was due; however, we stayed in the lab.

In the first sentence because introduces a dependent clause. The clause because the report was due cannot stand alone. In the second sentence, both sides of the semicolon stand alone as full clauses; the connector merely shows contrast between them.

These differences matter when you draw sentence diagrams, answer parsing questions, or join clauses in essays. When you say that a word is a subordinating conjunction, you usually mean that it turns the following clause into a dependent one. The word in question does not normally do that job when it shows contrast between two complete thoughts.

Item	Label In Modern Grammar	Typical Pattern
because	Subordinating conjunction	because + clause, joined to main clause
if	Subordinating conjunction	if + clause, joined to main clause
when	Subordinating conjunction	when + clause, joined to main clause
however (contrast)	Conjunctive adverb	clause; however, clause
however (manner)	Relative adverb	however + you/they + verb, main clause
and	Coordinating conjunction	clause and clause
that	Subordinator/complementizer	that + clause after verbs such as say, think

Notice that the table also lists that. Large reference works on English grammar treat this word as a classic subordinator in patterns such as She said that the data were wrong. That pattern differs from the one you see with contrastive uses of the word in question.

Practise Building Your Own Sentences

Labels make more sense when you attach them to real writing. Instead of only filling gaps in workbook exercises, write short paragraph pairs that show contrast. Use patterns such as clause; however, clause and However you do something, result clause, then check them against trusted references.

With these habits, you will keep a clear sense that the safest modern label for the word is conjunctive adverb or linking adverb, not core subordinating conjunction. Even more than that, you will know how to use it in clear, accurate sentences that match the expectations of exam boards, teachers, and academic style guides.
