Intrude is often used in reference to meddle . Who intrudes, therefore, take part in a theme or in a affair When it does not apply. For example: “My mother-in-law can't help but interfere in the relationship we have with my husband: she is always giving us ideas or criticizing”, “No foreign government is entitled to interfere in the internal affairs of our country”, “A spy was detected when he tried to interfere in the presidential delegation”.
By meddling, in short, someone participates in something without having authority or reason to do it. Suppose that, to a young man who works independently as a gasman, his parents spend giving him advice on how he should treat his clients, how much he has to charge for his service and other questions of his trade. The boy, tired of those intrusions, asks them to stop interfere in your work since he knows how it has to be handled.

As mentioned in a previous paragraph, we must not forget that one of the meanings of intrude it is used in the field of chemistry to denote the inclusion of one substance in another to achieve a mixture between both. In the previous list of synonyms, the corresponding ones for this meaning can be enter or mingle, provided that they are understood as substitutes for interfere, although the reflexive form is uncommon when talking about combinations of substances.
However, in the popular language the meaning that we usually give it is to participate in a conversation or a affair alien without having been invited to do so. To replace the word interfere in a case like this we can resort to interfere, get in, get in the way and, less frequently, to intervene.
These four terms are quite particular in this context, since almost all of them require an explanation to clarify certain issues. First we have intrude, a verb that is also used in its reflexive form to refer to the action to interfere, that is, to take part in a matter without authority; in many Spanish-speaking regions, it is used in an alternative version, "entror get in, "and the same goes for your respective adjective, in betweenwhose writing is preferred with a AND instead of the OR , "enteror stuck. "
The term get inOn the other hand, it is much more frequent than the rest, partly because of its smaller length. Just like the others, their reflexive form can decompose to give rise to sentences such as "I don't understand why he gets in / intrudes / intermeshes / interposes". In this example we also mention interpose, which can acquire the same meaning, although it is usually necessary to accompany it with certain data complementary. Finally is to intervene, which can also have a positive connotation, so we must know the context to understand the intention of the speaker.
