Examples:
- Henryk, my brother, makes the best steak tartare in the world.
- I can’t go to Spain until autumn, although I’d love to go there today.
- I thought he was mad, and had been for a long time.
- We need to increase sales , which means achieving better results than in the previous quarter.
In additions, the conjunction or rather often appears , which is intended to explain information to the recipient that they do not know about. Therefore, when asked whether we put a comma before or , the answer is yes. Similarly, a comma before: that is, in other words, should also be used.
In complex sentences containing at least two predicates, each component clause should be separated – by a comma, a conjunction, or a conjunction and a comma
In complex subordinate sentences we use:
- comma before so that – e.g. In the rcs data autumn season, you should use preparations with vitamin C in order not to get sick.
- comma before because – e.g. He didn’t go to school because he had a stomach ache.
- comma before by – e.g. Sign up for our newsletter to receive information about promotions.
- comma before when – e.g. We will ship your purchase as soon as we receive confirmation of payment.
- comma before how – e.g. He didn’t tell her how sorry he was .
- comma before which – e.g. I read a book that changed my life.
- comma before because – e.g. I couldn’t come to the meeting because I caught a cold.
- comma before that – e.g. I knew that would happen.
- comma before so as not to – e.g. Leave early so as not to miss the bus.
- comma before even though* – e.g. You are entitled to a discount even though you have a regular customer discount.
* Even though a comma appears before a two-word conjunction in a complex sentence, its individual components are not separated by an additional comma.
In complex sentences the situation is much more complicated, because the comma before the conjunction appears depending on the type of the sentence.
This applies to the following situations:
- in opposing sentences we put:
- comma before a – e.g. I went to collecting customer feedback is crucial to understanding consumer post a letter, and the post office was closed.
- comma before but – e.g. He didn’t have to do it at all, but he willingly took on the task.
- comma before but – e.g. I really like this dress, but I can’t buy it at the moment.
- comma before only that – e.g. I agree with this opinion, except that I have a few comments.
-
in the resulting sentences we put:
- comma before than – e.g. I prefer to marketing list spend time outdoors than stay at home.
- comma before so – e.g. She was tired, so she went to sleep quickly.
- comma before why – e.g. I don’t understand why you don’t want to talk to me.
Compound sentences joined by the following conjunctions are not separated by a comma:
- connectives: and, a (as a connector), nor, and , and, at the same time – e.g. I like travelling and I often go away.
- separable: or, either, be, whether – e.g. I will go on a trip or go to the cinema.
If a complex sentence contains a participle equivalent of the sentence (in the form of an adverbial participle), it must be separated by a comma.
Examples:
- Following him , he discovered his great secret.
- When he arrived at work , he drank his coffee and began sorting through the pile of papers lying on his desk.
