late Middle English: from Old French advers, from Latin adversus 'against, opposite', past participle of advertere, from ad- 'to' + vertere 'to turn'. Compare with averse.
Adverse means ‘hostile, unfavorable, opposed,’ and is usually applied to situations, conditions, or events—not to people: the dry weather has had an adverse effect on the garden . Averse is related in origin and also has the sense of ‘opposed,’ but is usually employed to describe a person’s attitude: I would not be averse to making the repairs myself . See also averse (usage).
