Preguntas frecuentes (8)
Yes! It is perfectly natural. Just remember to put a comma after the first part of the sentence. Example: `Because I was tired, I went to sleep.`
Usually, no. In standard English, we don't put a comma before `because` when it's in the middle. Example: `I'm happy because it's Friday.`
`Because` introduces the reason (I'm eating `because` I'm hungry). `So` introduces the result (I'm hungry, `so` I'm eating).
In casual speaking and texting, yes. In formal writing or exams, always use the full word `because`.
In informal speech, people sometimes say 'Because!' as a way of refusing to give a reason. However, usually, you should follow it with a sentence.
Use `because of` when the reason is just a noun. Example: `I'm late because of the rain.` Use `because` when the reason is a full sentence: `I'm late because it is raining.`
Yes, they are very similar. `Since` is slightly more formal and often used when the reason is already known by the listener.
It is a common abbreviation for 'because' used to save time while typing on mobile phones.
