[Middle English wel, from Old English; see wel-1 in the Appendix of Indo-European roots.]

Usage Note: English speakers have used well both as an adjective and as an adverb since Old English times. When applied to people, the adjective well usually refers to a state of health. Like similar adjectives, such as ill and faint, well in this use is normally restricted to the predicate, as in He hasn't been well lately. Well does see occasional use before a noun, as in Benjamin Franklin's "Poor Dick eats like a well man, and drinks like a sick." It also appears in compound adjectives like well-baby and well-child, which are widely used by health-care providers. Good, on the other hand, has a much wider range of senses, including "attractive," as in He looks good, and "competent," as in She's pretty good for a beginner, as well as "healthy." See Usage Note at good.
