obstrict (<<schwa>>b-strikt), vb. To coerce. — obstrictiveness,n. — obstrictive,adj.
“The element of coercion or obstrictiveness. The contrast here is between voluntary and obstricted (or coerced) conduct. The coercion need not be actual (objective), but may be merely potential (subjective) by fear of the possible force; as, when the faithful canine, Towser, susceptible to the sight of a feline enemy, is tempted to pursue, but upon his owner’s stern voice and a shake of the stick, Towser turns humbly back and crushes his impulse.” John Henry Wigmore, Problems of Law 7–8 (1920).
