Did you know?

In inimical, one finds both a friend and an enemy. The word descends from Latin inimicus, which combines amicus, meaning "friend," with the negative prefix in-, meaning "not." In current English, inimical rarely describes a person, however. Instead, it is generally used to describe forces, concepts, or situations that are in some way harmful or hostile. For example, high inflation may be called "inimical" to economic growth. Inimicus is also an ancestor of enemy, whereas amicus gave English the much more congenial amicable (meaning "friendly" or "peaceful") and amiable (meaning "agreeable" or "friendly").
