The French saying “bec et ongles” derives its origin from the Latin expression “rostrum et unguibus,” which also means “beak and nails.” This ancient phrase refers to the beak, symbolizing the fierceness and determination of a bird, and the nails, representing strength and tenacity.

Throughout history, birds have often been associated with bravery and courage, and their physical attributes have served as metaphors for human characteristics. The beak and nails of a bird reflect its readiness to defend itself fiercely, using all available means to protect its territory or achieve its goals.

In terms of English equivalents, the phrase “tooth and nail” closely resembles the meaning of “bec et ongles.” It signifies a strong determination to fight or defend oneself vigorously, using all possible resources and means available. Another related expression is “by hook or by crook,” which suggests a willingness to do whatever it takes to achieve a desired outcome, even if it involves unconventional or questionable methods.
