The Chinese word "号啕大哭" is formed by combining the binome "号啕", where both characters individually mean to wail or cry out, thus reinforcing the notion of loud weeping, with the phrase "大哭", meaning to cry loudly. The juxtaposition merges these similar semantic elements, with "号啕" acting as an intensifier for "大哭", resulting in a compound that vividly describes vehement and audible sobbing.
