Nowadays, people are experimenting to use lots of uncommon words in their sentences making it difficult to understand by a common man. How do we understand the meaning of a sentence having words that we are not familiar with? Is there any solution for understanding those sentences?
This raises an interesting question: Is using a less common word a good thing, or a bad thing?
On one hand, when we use less common words, we risk making a sentence more difficult to understand. Mark Twain once advised, “Don't use a five-dollar word when a fifty-cent word will do.”
On the other hand, if all language was reduced to its simplest form, our paragraphs could become dull and puerile.
So, how can we understand a sentence with an unfamiliar word? Context often helps. I may not be familiar with the word cochineal, but if I saw it in a sentence like this one:
The cochineal sky reflected off the water at sunset.
I might (incorrectly) guess that the word means something like "cloudy". If I'm astute enough to realize it's referring to a color, I can guess the color matches a color often seen at sunset.
Why would a writer use cochineal instead of red? Sometimes a more unusual word sets a tone; sometimes it infuses a degree of descriptive precision. There may be 20 shades of red, but not all of them suggest the deep vivid carmine of cochineal.
One fundamental piece of writing advice is, "Know your audience." If I am giving a formal talk at a scientific conference with a large contingent of internationals, I might simplify my flowery language, knowing that many attendees may have limited vocabulary. However, I would be less likely to simplify my technical language, since the attendees are presumed experts in the field. On the other hand, if I'm writing a fictional work about quests and dragons and swords and kings, I would be more likely to use language that helps the reader get lost in my imaginary world, and less likely to talk about, say, quantum entanglement.
When context and all else fails, a good dictionary can be a very good friend.
