Some compound words (like bus rapid transit, dog whistle, or identity theft) don’t appear on the drop-down list when you enter them into the search window. If a compound term doesn’t appear in the drop-down list, try entering the term into the search window and then hit the search button (instead of the “enter” key). Alternatively, begin searches for compound terms with a quotation mark.

Share:
tr.v. im·peached, im·peach·ing, im·peach·es
1.

2. To raise doubts about; discredit or disparage: impeach a witness's credibility; impeach someone's character.

[Middle English empechen, to impede, accuse, from Anglo-Norman empecher, from Late Latin impedicāre, to entangle : Latin in-, in; see IN-2 + Latin pedica, fetter; see ped- in the Appendix of Indo-European roots.]

im·peacha·ble adj.
im·peacha·bili·ty n.
im·peacher n.
im·peachment n.

Usage Note: When an irate citizen demands that a disfavored public official be impeached, the citizen clearly intends for the official to be removed from office. This popular use of impeach as a synonym of "throw out" (even if by due process) does not accord with the legal meaning of the word. When a public official is impeached, that is, formally accused of wrongdoing, this is only the start of what can be a lengthy process that may or may not lead to the official's removal from office. In strict usage, an official is impeached (accused), tried, and then convicted or acquitted. The vaguer use of impeach reflects disgruntled citizens' indifference to whether the official is forced from office by legal means or chooses to resign to avoid further disgrace.
