One of the essential requirements to write correctly is to know the spelling of the language in which we express ourselves. However, it is normal that, from time to time, doubts arise about the writing of certain words whose spelling can be confusing or not very intuitive. The most effective way to improve this problem is to read constantly. However, whenever you have any questions, you can consult many of the unCOMO articles on the subject.
In this case, we are going to answer one of the most common queries in the Spanish language, how to spell: did I start or did I start? Read on and find out how to write the past tense of the verb to begin well and discover the reasons behind its spelling so that you know how to write similar conjugations. Go for it!
The correct way to write this word is I started. It is the first person conjugation of the past tense of the verb start, which always has an accent in the last letter e. If you have doubts about How to use accentsWe invite you to clarify them by clicking on the link!
Now, according to the definition of the RAE, the word begin has the following meanings:
- Start something. Example: I started the first semester of university.
- Initiate the use or consumption of something. Example: I started to eat healthier.
- Said about something: It has a beginning in a place. Example: many words begin with the letter c.
- Said about something: Start in time. Example: summer starts in July.
As you can see, the word to begin has the same use of the verb to begin, since both are synonyms. Other synonyms for begin include:
- Start
- Undertake
- Start
- Give beginning
- To start.
Did I start or did I start?
Since one of the most common synonyms for the verb to begin is precisely the verb to begin, it is normal that there are also doubts about its correct conjugation. Both verbs follow the same rules of conjugation, like other irregular verbs like hit. Therefore, it is written I started and I did not start.

If the verb to begin is written with the letter z, why is it written to begin? Since Spanish speakers do not distinguish between the pronunciation of z and c, it is common to find these types of misspelled words. In addition, the word started has the added complication that its infinitive form is written with z. Put like this, how can we know when a word is written with z or with c?
Spelling rules for z and c
In general, we can follow the following rule: the word is written with z if it is followed by the vowels a, uoa, as is the case with the verb start. Instead, the word is written with c if it is followed by the vowels eoi, as happens with the conjugation I started.
As with many spellings in Spanish, there are exceptions to the rule. Some words are written in contradiction to the rule to preserve the spelling of the original language from which they come. Some examples include words like Nazism, Zigzag, or Zeugma.
On the other hand, all verbs whose infinitive form ends in -zar, change the z for the c before the letter e, as for example the verbs analyze (I analyzed), embarrass (embarrassed), canalizar (canalicé) and use (utilicé).
It is normal to find other words written with both z and c, such as zebra and zebra, zinc and zinc, zygote and zygote, magazine and magazine, among others. However, in many of these cases, the RAE recommends one spelling over the other, since one of them has fallen into disuse, as is the case of zebra or zebra.
Note that the letters s, z, and c tend to have many exceptions when it comes to their use. Not all words with eoi will have a c after it, for example. The best way to learn Spanish spelling is by continually reading so you never forget how to spell a word, or by consulting the spelling rules of the language.
For example, another of the most common doubts is how to write the past tense of the verb to do in the third person singular: ¿¿did or did? In this case, the correct way is made. However, when we talk about the conjugation in the past of the verb want, it is written wanted and did not want, since all verbs whose infinitives do not contain s, c or z are written with s.
In other cases, there are homophone words that, although they are pronounced exactly the same, are written differently. For example, you can write slash or pink, both words have different meanings, but sound the same when pronounced, so it is easy to confuse their spelling.
