To deepen is a word whose meaning varies according to the context in which it is used. Its most common use refers to deepen or dig deeper into something or a situation that indicates a physical space or a symbolic situation.
For example, “The hole had to be deepened a little more so that it was possible to build and seat the commune of the building,” “In the interview they wanted to delve into my personal life.”
Another of the deepening uses indicates digging or introducing something deeper than what is found. For example, “You have to dig deeper into the earth to find the requested minerals,” “The mechanic had to delve his tools into the engine of the machine to be able to remove the broken parts.”
The use of the word to deepen that it indicates to introduce can be applied in diverse areas like, for example, “During the surgery the doctor deepened his clamp in the patient to introduce the prosthesis”, “In the search for evidence, the biologists delved into the caves to take samples of land ”.
On the other hand, when an investigation is carried out or finding information on a particular topic, researchers generally seek accurate information and delve on it to demonstrate or explain the causes or consequences of something.
For example, “The school psychologist is doing an analysis of the behavior of children between 6 and 7 years to delve into how they communicate and develop socially”, “In my thesis I deepen the importance of the use of social networks publicity and marketing”.
The same happens in the area of social communication when a journalist conducts an interview, documents a story and carries out a series of questions in order for the interviewee to provide the desired information.
For example, “During the press conference several journalists wanted to delve into the new film, but the director did not comment further,” “I am going through a difficult time in my life and I am not going to delve into it during the interview.”
The word deepen can be substituted for these synonyms as necessary: dig, deepen, undermine, probe, descend, investigate, interrogate, address, etc.
