The meaning of every word is usually much beyond the dictionary meaning.
There are so many large contexts and meanings associated with each word.
Every word abstractly is a pointer to a kind of knowing.
So when I want to convey something, I use many synonyms to point at ‘scope and essence’.
Essence = Intersection.
Scope = Union.
For instance: Consider a set like ‘God/Reality/Existence/Field’.
Here, essence = intersection of the meaning-images in the set.
And scope = union of the meaning-images in the set.
I see every word as pregnant with a large amount of connotation/meaning/context/associations.
The use of sets of synonyms thus serves as a communication technique/device for me to convey scope and essence.
