Etymology of WELLDEFINED
The word "well-defined" is a compound word formed by combining the adverb "well" and the past participle of the verb "define".
The term "well" is derived from the Old English word "wiel", which means "in a good manner or manner of prosperity" or "to a high degree". It has remained relatively unchanged in its meaning throughout history.
The verb "define" is derived from the Latin "definire", which means "to set bounds to" or "to limit". It is formed by combining the prefix "de", meaning "down" or "away from", and "finire", meaning "to finish" or "to limit".
Thus, the term "well-defined" literally means that something is defined in a satisfactory or clear manner, with specific boundaries or limitations.
