#to bend

• Bend — To incline, lower, or bend a part of the body or an object from a vertical position into an oblique or downward direction; as a reflexive verb, it represents the action of bending one's stature as a sign of respect, greeting, or reverence. Figuratively, it expresses the mental action of dedicating oneself, studying with close attention, analyzing a phenomenon in depth, or demonstrating goodwill, condescension, or structural submission toward an authority.
• To arch — To give an object the shape of an arch, to curve, bend, or vault mechanically; to bend under the weight of a load or under the action of an external force, acquiring a concave or convex line. In a structural sense, it defines the property of an elastic body to deform temporarily without breaking and to subsequently return to its original shape.
