The phrase "backing and fill" refers to a nautical term describing the movement of a ship when tacking against the wind. The tandem words are spelled with the IPA phonetic transcription /ˈbækɪŋ/ and /fɪl/. The word "backing" is pronounced with the "a" sounding like that of the word "cat" and the "i" sounding like the word "bit." The word "fill" is pronounced with the "i" sounding like that of the word "pill." Together, they form an idiomatic expression used outside of nautical contexts to describe indecisiveness or lack of progress.
"Backing and fill" is an idiomatic expression used to describe the act of changing one's opinion or position frequently or inconsistently, especially in response to pressure or changing circumstances. It implies vacillation, indecisiveness, or wavering between different sides or viewpoints on a particular issue.
The term originates from nautical jargon, specifically the practice of maneuvering a sailing vessel in a narrow channel or tight space. "Backing" refers to turning the vessel's stern toward the wind, while "filling" refers to turning the vessel's bow into the wind to regain forward momentum. Therefore, "backing and fill" suggests a continuous series of abortive maneuvers to steer the ship in the desired direction.
In a broader sense, the expression is used metaphorically to describe similar actions in non-nautical contexts. It characterizes individuals or entities who repeatedly change their stance, either due to external pressure or their inability to commit to a particular position. This behavior may stem from a desire to please everyone, a lack of conviction, or a fear of backlash.
Overall, "backing and fill" relates to shifting opinions or positions to avoid confrontation, maintain popularity, or simply due to a lack of a solid stance. It suggests a lack of consistency and can imply a certain level of distrust, as individuals using this tactic may be seen as unreliable or insincere in their beliefs.
