Learning to write correctly, that is, without spelling mistakes and with impeccable grammar, is a basic aspect of language learning. However, there are those who find it very easy and to whom it may seem quite confusing, something that also depends on the language and what our mother tongue or native language is.
For example, Spanish is considered one of the most difficult languages to learn for those whose mother tongue is a language that is not of Latin origin. Whether it is a child starting to learn Spanish at school or an adult expanding his knowledge of languages, in this language there are very common mistakes when the use of some letters is confused. For example, when to use a silent h at the beginning of a word or to differentiate when to write I ll, as is the case of doubt when writing “yesterday”, “aller” or “hayer”.
To help you improve your writing, at oneHOWTO we have prepared this article in which we clarify that the correct way is to write “yesterday” with and Greek and without h, in addition to illustrating it with example sentences. Keep reading and learn how do you spell yesterday, aller or hayer.
How is it written yesterday and its meaning according to the RAE
To find out if a word is written in a different way, the correct thing to do is to look for it in Dictionary and even better if we look at it in the RAE or Royal Spanish Academy, which is in charge of registering all the words, among other functions.
Thus, before the doubt of how do you spell yesterday, aller or hayer, the best thing is to consult your dictionary or DRAE (Dictionary of the Royal Academy) and give us, in this way, learn that the correct form is “yesterday” with and Greek and without h.
Specifically, the meaning of “yesterday” according to the RAE is that it is a word of origin in Latin (ad heri) and that has several meanings, mostly as a demonstrative adjective, but only in one case as a masculine noun. These are its basic meanings:
- The day that immediately precedes or precedes today.
- Regarding the past or something that has happened in the past.
- Past time.
Examples of correct sentences with the word “yesterday”
- Yesterday I went to the cinema with my brother and we saw a movie in its original version.
- Do you remember what we said yesterday about schedules?
- What did you eat for breakfast yesterday? I had a coffee and had a sandwich.
- Yesterday it was very cold.
- Yesterday I bought a t-shirt at the mall and today I have to return it.

* Aller
It is common confuse the greek y and ll because sometimes they can be very similar frantically, that is to say when pronouncing them.
In the case of the word “yesterday”, is only correct with and, so if we go to the DRAE or Dictionary of the Royal Spanish Academy, we see that the form with ll, that is, “aller” does not exist, is not correct and, therefore, should not be used in any context, since in Spanish it is not a proper name of person or place.
* Hayer
As we saw at the beginning, another form with which there is usually confusion is the word written with a Greek y and with an h at the beginning, that is, “hayer”. Again, by going to the DRAE (Dictionary of the Royal Spanish Academy) we can look up the word written like this and we will see that “hayer” does not exist.
Thus, as it is not a proper name of a person or place in Spanish, this word must never be written in this way, only “yesterday” is correct.
