Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct word-for-word translation from Russian complex sentences with conjunctions 'потому что', 'так как', 'если', as English requires strict clause order and subordinator choice.
- Russian may use a comma where English requires a subordinating conjunction.
- The concept of a 'clause' being a subject-predicate unit is key; a single adverb word is not a clause.
Common Mistakes
- Using a comma to connect an adverb clause to the main clause when it follows the main clause (e.g., 'I went home, because I was tired.' - the comma is often unnecessary).
- Confusing it with a prepositional phrase (e.g., 'After the meeting' vs. 'After the meeting ended').
- Using an incorrect subordinator for the intended meaning (e.g., using 'while' for contrast instead of time).

FAQ
Frequently Asked Questions
Yes, in modern grammar, 'adverb clause' and 'adverbial clause' are generally used interchangeably to describe the same structure.
Yes. When an adverb clause begins a sentence, it is usually followed by a comma (e.g., '**Because he was late**, he missed the introduction').
Subordinating conjunctions such as: because, if, when, although, while, since, until, unless, wherever, as, etc.
Yes. By definition, a clause contains a subject and a predicate. An adverb clause is a dependent clause, so it must have its own subject and verb, even if the subject is implied in some rare elliptical constructions.
