Delving into the study of the word "in communication", it is worth noting that it is written separately in any case. But let's take a closer look at this word. In Russian, prepositions are not significant parts of a sentence, but they express the relationship in it. The preposition "in connection" is causal, that is, it expresses the reason for any action: "In connection with this event, we decided to move to another city" (because of this event - the reason).

In addition, between the preposition and the noun can put an additional word, which can not be done in the preposition: consisted in a long connection.
