You can only sense something that is there (somewhere, in or out). And, one attempts to name what one senses in order to identify, record, express, and connect. From sensation to idea formation to naming to expressing is an incredible journey. In most cases, existing names are identified and matched with subjective sensations. In most cases, as well, these identifiers get modified to represent and establish newer sense-ideas. Thus, word meanings get enhanced and extended, or may become obsolete or replaced. In other cases, words are imported where there is a lack, and in some cases, created or recreated.
