mit′i·ga·ble (-gə-bəl) adj.mit′i·ga′tion n.mit′i·ga′tive, mit′i·ga·to′ry (-gə-tôr′ē) adj.mit′i·ga′tor n.Usage Note: Mitigate, meaning "to make less severe, alleviate" is sometimes used where militate, which means "to cause a change," might be expected. The confusion arises when the subject of mitigate is an impersonal factor or influence, and the verb is followed by the preposition against, so the meaning of the phrase is something like "to be a powerful factor against" or "to hinder or prevent," as in His relative youth might mitigate against him in a national election. Some 70 percent of the Usage Panel rejected this usage of mitigate against in our 2009 survey. Some 56 percent also rejected the intransitive use of mitigate meaning "to take action to alleviate something undesirable," in What steps can the town take to mitigate against damage from coastal storms? Perhaps the use with against in the one instance has soured Panelists on its use in the other. This intransitive use is relatively recent in comparison with the long-established transitive use, so novelty might play a role as well.
