What is the meaning of the word constrict?

The term "constrict" means to make something narrower, smaller, or tighter. It often refers to the action of muscles or other structures in the body that help close or tighten an opening, thus reducing its size. In this context, "tighten" directly captures this essence of reducing width or scope, which aligns perfectly with the definition of "constrict." The other options do not share this meaning: "collect" implies gathering together, "appreciate" denotes recognizing value or significance, and "minge" indicates coming together or mixing, which are all unrelated to the concept of tightening or narrowing. Therefore, "tighten" is the most accurate representation of the meaning of "constrict."
