Surely you have ever stopped writing for a thousandth of a second to ask yourself if you had to write “why” together or separately and with or without an accent. You may be surprised to learn that all forms are correct, as long as you know when to use them well. All can be used as long as you are clear about the context in which you should do it.

When do we use because, why, why or why

All forms are correct although you do not have to make mistakes in their use. Why, because, why or because they belong to various categories of words and their usage is also different. When you remember once when each of these words should be used, you will never make a mistake again.


It is an unstressed conjunction, and that is why it is written without an accent mark. When is it used?

  • As a casual conjunction. This means that it is used to introduce subordinate phrases that express cause. Example: “I didn’t want to eat at noon because my stomach hurt”. This conjunction can be changed in the sentence to “since” or “since” without changing the meaning of the sentence. Example: “I didn’t want to eat because my stomach hurt”.
  • As a heading for answers to questions that start with “why”. Example: “Why did you go to his house? – Because he had to give me my jacket.”.


It is a masculine noun synonymous with “cause”, “reason” or “reason”. It is an acute word ending in a vowel, that is why it has an accent mark. Like all nouns, it is used preceded by an article or other determiner, and it has its plural. Example: “I never knew why he hurt me so much. / You will have your whys to go that way”.

Write because, why, why or why


It is the sequence that forms the preposition “por” and the interrogative or exclamatory “what”. It is used in direct interrogative or exclamatory sentences or indirect.

  • Direct: are those with question marks or exclamation marks. Example: “Why didn’t you call me last night?”.
  • Indirect: are those that do not have question marks or exclamation marks and depend on the verb principal. Example: “I want to know why you didn’t call me last night”.


This form occurs in two cases that you must recognize :

  • Preposition “por” + relative pronoun “que”: In this case, the article is usually placed before “que”. Example: “It is the reason why I did not go last night”.
  • Preposition “por” + subordinating conjunction “que”: is used with verbs or adjectives whose complement is introduced by the preposition «por». It also has a subordinate clause by the conjunction “que”. Example: “I’m sad that the children can’t come with me”.

From now on you won’t have any problem differentiating when you have to write any of these four ways. It’s easier than you think, as long as you remember when you should use each of them. Once you remember, you’ll never go wrong again!
