The words are parts those contain the our ability to express thoughts, opinions, statements etc. However words are not so obvious like they seem.
In regular situation, always it is easy to find the right words to describe what happening.
Occasionally, we involved in some cases, that we must deliberately choose the words, as our set of ones can drive to an unexpected outcomes.
Between two or more speakers language is the same, but understanding is different.
Receiving some verbal information from speaker related with dedicated deciding of listener what these specific words are mean.
If you want to be understandable by your listeners, you should be aware of this.
People are not linear, and maybe all the time, they use different words even describing the same thing.
