wellness noun.

– origin OE wel(l), of Gmc origin; prob. rel. to the verb will1.

usage: The adverb well is often used in combination with past participles to form adjectival compounds. The general stylistic principle for hyphenation is that if the adjectival compound is placed attributively (i.e. before the noun), it should be hyphenated (a well-intentioned remark) but that if it is placed predicatively (i.e. standing alone after the verb), it should not be hyphenated (her remarks were well intentioned). In this dictionary, the unhyphenated form is generally the only one given.
