There are many big words in software engineering that describes rather simple concepts, while it's understandable that these words help in referencing some concepts that are too long to explain, in a way, it overwhelms code newbies. On the other hand, clients are somewhat impressed by esoteric terms like that, especially when you can explain it very well.
Let's look at the term known as "string interpolation", first time I saw this I assumed it had to do with something from outer space. I quickly learned that it was a more convenient way to insert variables (which can change frequently if that variable fetches information from a database) in a sentence especially when that variable holds information that is needed to give the sentence meaning.
A more realistic example is how auto-generated emails sometimes have your name in the content or how you're able to access information that is specific to you yet uses sentences that is general to everyone, the previous method of coding such a response was rather clunky which is why string interpolation is important.
You can make you of string interpolation by using a special symbol (usually $) before the quote beginning the string and reference the variable name within a curly bracket, different languages might have their style however the concept is the same. String interpolation makes code look neater thus making it easier to read and maintain.
