All words have meanings, but not all meanings have words.

It's a fairly natural tendency, or perhaps common tendency, for one to go around defining things. Defining in fact everything. As an incurable writer I have this affliction. I want to find and understand the meaning of the words I encounter. I want to find new words to use. I want to find the precise words to precisely describe a precise set of circumstances.

But.... There's always the "but". 

But sometimes I wonder if it wouldn't be better to throttle back and be more selective in what I choose to define, and let other things just be. 

Are there in fact some things which defy description? Meanings that have no words? Meanings that can only be felt or hinted at or sensed as nearby?
