The knowledge we acquire through the study of grammatical facts sometimes leads us to the following observation: more than apprehending them, it is necessary to understand about the reasons that conceive them as such. Thus, based on this premise, it is worth emphasizing that this is a diversity of them and that mentioning them in their entirety would be too unfeasible, considering this meeting of ours. Thus, we chose as a priority for our discussion the close relationship established between the use of crasis and verbal regency.
In this way, the understanding that is established about the conceptual aspects, especially those that to the addition of the article "a" + the preposition "a" they become insufficient, concise and somewhat superficial. In this sense, the following question emerges (or at least needs to emerge): the presence of the preposition is due to exactly what? Well, it's simple, just stick to the following examples:
we will Àbeach, in case it doesn't rain.
We deliver orders THOSE ONEScustomers.
Analyzing both verbs, from the perspective of conducting, we find that, according to the predication, they are classified as indirect transitives, namely:
who goes, goes somewhere, hence “to the beach”.
who delivers, delivers something to someone, hence “those customers”.
As you could see, nothing exceptional guides the precepts attributed to this linguistic occurrence, given that just a little more analysis about the knowledge previously acquired (regency) to find the reasons for this or that classification.
