The phrase "did an about face" is a common idiom meaning to suddenly change direction or reverse one's course. The word "about" is pronounced with a schwa sound followed by a voiced bilabial stop /b/, while "face" is pronounced with a long a sound followed by a voiceless alveolar fricative /s/. In IPA phonetic transcription, the phrase would be written as /dɪd ən əˈbaʊt feɪs/, with the stress falling on the second syllable of "about".
The phrase "did an about face" refers to a swift and complete reversal in direction, opinion, or action. It is often used figuratively to convey a sudden change or turnaround in one's stance, behavior, or approach.
This expression originates from military terminology, specifically from marching commands. In a military drill, a soldier executes a precise and disciplined turn by facing in the opposite direction. The phrase "about face" is the command given to initiate this movement. Therefore, when someone "does an about face" metaphorically, they are metaphorically executing a similar turn, abruptly changing their position.
The phrase can be used to describe a person altering their opinion on a particular matter, performing a complete change in behavior, or reversing a decision. It implies a quick and often unexpected shift in perspective or course of action. For example, if a politician initially supports a policy, but later, due to public pressure or new information, renounces their support and takes the opposite stance, they can be said to have "done an about face."
The term "did an about face" encapsulates the notion of a sudden and complete reversal, highlighting the drastic change in direction, attitude, or action. Its usage illustrates the reversal as being swift and decisive, often emphasizing the surprise or unexpectedness of the transformation.
