On your marks, get set, get started!

In Spanish, there are three verbs to talk about starting an action: Iniciar, Empezar and Comenzar. Although there are subtle differences that we may talk about in another article, today we are going to talk about the last one we named, the verb Comenzar. Despite sharing etymology with the verb to commence in English, as both come from the Vulgar Latin cominitiare, Comenzar is often used more like the verbs to start or to begin. Although, like its cognate (a nice word to talk about sharing etymology), it also tends to be less commonly used than the verb Empezar, which is considered common or colloquial. Now, shall we begin?

I start to Notice an Irregularity

Of the three verbs we were talking about before, Comenzar and Empezar share not only the meaning (they can be used one or the other without any problem), but also their irregularity. Both verbs have a vowel irregularity and a grammatical irregularity. The first one we are going to see as follows:

  • e -> ie, for example: we do not say “Yo comenzo”, we say “Yo comienzo”.

And the second one like this:

  • z -> c, when it is followed by an E or I, for example: We do not say “(We) Comenzemos”, but “(We) Comencemos”.

Verbals of Comenzar

If you think of verbs, the first thing that comes to mind are conjugations, but what if I told you that not everything is what it seems? A Verbal, although born from a verb, no longer works in the same way, that’s why they are no longer conjugated! In total there are 3 types of Verbals: the infinitive (used as a noun), the gerund (used as an adverb) and the participle (used as an adjective); let’s see them!
