An influence or power that makes someone do what they wouldn't normally do can make them sway.
When we talk about someone swaying, we usually mean that they are being persuaded to think or act a certain way. This could happen because of words from another person - like a salesperson trying to get you to buy something. It's like the other person has some power over your thoughts and feelings, making you lean in one direction rather than another. Imagine a tree swaying gently in the wind - it's not being pushed or forced, but it's moving because of an outside force.
To move or swing from side to side; or backward and forward; to rock.
Example: sway to the music; The trees swayed in the breeze.
Bent backwards, as in swayback
