noun, usually 'manacles'. A metal band, chain, or shackle for fastening someone's hands or ankles.
verb, transitive, usually 'be manacled'. To fetter a person or a part of the body with manacles.
From Old French manicle, meaning 'handcuff' and from Latin manicula, a diminutive of manus, meaning 'hand'.
Panicking, he picked up the rifle and checked it for damage before he turned his attention to his painful wrist. It was probably sprained instead of broken. Time would tell. Only then did he roll onto his back, sit up and look at his feet to find the cause of his fall: a tangle of greenbriar vines wound around both ankles and manacled them. He tried to retract one foot and was surprised when the vine held. Tough plant.
Aware that the men he was tracking could be close, he whispered a curse and lay the rifle aside so he could use his hands to free his feet. Wincing as the thorns pricked his ungloved fingers, he worked the vines loose and drew both feet close so he could test his weight on them before he rose. No pain there, but he would have to avoid putting pressure on the wrist. Thank goodness it was the left one.
He was about to stand when he heard a twig snap. He settled into a crouch and swiveled slowly, scanning the trees and brush around him for a human silhouette.
